I have actually had some similar experiences, not to the same extent I would say, as far as actually engaging, but in the conclusions that I cam do as direct results of their teachings.
My father is an atheist, and my mother catholic, which lead to an interesting upbringing. My father was always pretty sceptical, at least when it came to supernatural/religious issues, but, like many sceptics, never really took it to the same level when it came to the state. Also, he was never too vocal about it, which was interesting. I guess he took more of a hands off approach to encouraging me to make my own decisions on these things. So, not encouraging me to think one way or the other, but also not even being too vocal about encouraging me to question things.
He did not hold back his own opinions, though never really pushed them.
I almost wish he had been a bit more vocal about some of them, as it may have brought me to atheism sooner, though it may also have put me off.
My mother also was quite encouraging (perhaps allowing of, as she also was never too vocal about it, just never discouraging) about having my own opinions.
Any who, one of the major things I learnt from them was essentially that something was wrong when it hurt someone else. This, I would say, was probably the main thought that lead to my understanding of ethics. It is also what lead me to the two major contradicting conclusions relative to my parents thoughts, in spite of said conclusions being based on a principle they both advocated.
So, my father is militantly against all forms of recreational substances. This includes alcohol, and cigarettes, he thinks both should be illegal. Now, I used to be the same, I never drank underage, but felt I should at least try it when of age before deciding if I would ever drink, and even avoided having friends that i knew smoked pot untill college, when I realized this was a near impossible goal, lol.
So, of course, after college, I was becoming a bit more "liberal," in the traditional sense on my thoughts towards pot, and but still apprehensive about treating harder drugs the same, which changed when I realized that I simply was not applying the same critical thinking, and principles to them as I was everything else. The same thought process lead to me realizing that I was so liberal for peoples rights with their own bodies, but still advocating health care and such, and I realized the contradiction of principles there too. I supported freedom with your body, but was advocating denying that freedom with your money, which was also a direct result of what you did with your body.
So, clearly it did not make sense to consider these things wrong as there was no harm being done to someone else. Completely consistent with what my parents taught me. This of course did NOT mean it was something I would advocate people choosing to do, just their right to do it. The same way I advocated your right to hit yourself in the face, but would not advise you do it.
This conclusion, obviously, is not something my father agrees with, and so, I recognize it as a conclusion he has come to based on personal feelings and biases rather than his own principles. Though, I saw a shimmer of hope in his eyes when I brought up how there was much more danger around alcohol during prohibition than when it was/is legal. At first he thought I was saying that there was more danger around alcohol back then than there is around drugs now, which he denied, but when I corrected him on what I meant, that I was comparing alcohol then and now (and even right after prohibition) I saw that glimmer of understanding. I didn't push it, but the seed was planted.
Any who, with my mother, the conflicting conclusion was on homosexuality. I made an off hand comment, saying "not that there's anything wrong with it" when discussing a high school friend's "experimental" phase if you will. This was a friend of mine that my mother always liked, and actually wanted me to date in high school. She actually already learnt about her dating a girl, and never seemed to hold that against her, to my mom's credit in a small fashion, but her true thoughts on the issue came out after my off hand Sienfielding allusion.
She responded "Excuse me? Yes there is!" This lead to a long heated discussion in which I argued that there was no harm in it, and she denied it had naything to do with religious influence.
Again, given that I came to these conclusions based directly off what she taught me, I was flabbergasted. My father's thoughts on drugs and such were a bit easier to understand given the far more popular negative opinion of them in general public, as well a his exposure to the worst of the worst with regards to drugs and booze given his work in corrections. My mother, on the other hand, just seemed nuts, lol. Especially as I knew she had gay friends.
Any who, since then, my mother has become a bit more accepting on the issue. She still has some personal "problems" with it, really just her being uncomfortable with it, and not processing that properly, and instead trying to make it an ethical issue, but she certainly seems a lot less hostile about it.
Of course, before our discussion, I never saw that hostility either, so who knows. Basically, it only manifests in that she expresses that she would not be comfortable with public displays of affection in her own home. She loves Will and Grace, so she clearly can see it in general, but accepting it in her home, in front of her, she still is not dealing with.
She is similarly uncomfortable with overt heterosexual displays in her house as well, though her tolerance level is greatly skewed. Basically, she doesn't care for me making out with my wife at the dinner table, but kissing, and general affection is never complained about. My mother and father are actually quite affectionate in front of others themselves. She just clearly is not dealing with the "skin crawl" factor, if you will, with seeing same sex kissing etc.
Any who, not trying to defend either of my parents views on the above, but rather trying to focus on the glimmers of hope they show. It's like talking with minarchists. They're walking in the right direction, but just not quite fast enough, or far enough.
I think it is all very telling of how people in general are struggling with their own principles. But it is also telling of how it is getting better with each generation. It makes me often wonder, will there be anything that our children "accept" that we are still struggling with? That is, what, headed forward, so not like our children holding onto statism, but is there anything left? What will be the next generations gay marriage/legalize pot issue that we might take exception too? Of course, I know it will not be the next "generation's" as the "generation" as a whole is not where many of us are in the liberty thinking.
It's feels arrogant to say that we've gone all the way. It feels like saying that we are the one's who have figured it all out, lol. But there are definitely things that each generation seems to be more accepting of than the previous. What IS there that my kids could be more accepting of that i am not? Of course, I'd like to think that this could be confined to moral issues, but if that's the case, then anything I don;t agree with them on it will likely be something I consider immoral. Bit of a self fulfilling prophecy. Any who, what is there that my kids could be RIGHT about that I will take issue with, lol.
