Rubystars,
For the most part I understand what you are saying. Family is very important in order to feel connection. Our families should be the closest things we have, as they say blood is thicker than water... But everyone I know has had very troubling issues with their parents. My ex-wife had issues which did not permit communication with her parents (or else it would hurt her). I don't want to get into the specifics, but it is because of this experience along with my own experience with my parents that i offered the advice i did.
People change over time and it is in my case that my father changed, I changed, and my mother changed... We all changed in different ways, but in the end I had a good relationship with my father till his death. My mother I call every week, and I even get along with my step-dad (who has cancer now) who I did not like when I was young.
We need to be surrounded by healthy thoughts, healthy acts, and connection to community... If hearing your family espousing such terrible ideas causes one to feel bad, it may be best to try to get out of the situation.
I could not stand hearing anyone, let alone my family, speak such terrible things...
