To answer the first reply, I would say that I've always been pretty honest with my family, and we get along reasonably well.
To Michael.J - Maybe I didn't phrase my post the way I had intended to, "stuck" probably wasn't the right word. But the reason I believe it is important (at least for me) to value my family of origin, is because they, much like any other parents, didn't choose to form a relationship with me anymore than I did with them. Sure, they probably intended to have a child, but they didn't even know what gender I would be, let alone what kind of personality, beliefs, etc. that I would have. But, just as billions of parents all over the world have done, my parents loved me anyway. It would seems selfish to me to abandon a relationship with my parents despite the years of sacrifice they have made in order to raise me.
According to the definition of love that you gave (which I have to admit I've never heard), I guess it would be impossible to love someone who you found no virtue in. By the way, is that a widely used definiton of love, is it from something, or is it your own personal definition? Either way, I would choose to disagree with it, because I have seen examples of "families of origin" loving each other despite characteristics that contradict each others values. (i.e. - baptist minister with son who is a homosexual). I've seen parents and children alike even change their own values to accomodate their loved ones, so love, to me can be stronger than personal values.
