What have I said to bring you to that conclusion? I have standards and base my relationships on them, same as everyone else. I judge the people around me on their actions, behaviour and thoughts and strengthen/weaken the relationships as I see fit.
Doesn't everybody do the same?
I don't want to be friends with someone who's had abortions because they forgot to use contraception, or parents who allow their children to change gender, or people with racist views or people who smoke etc. those are my standards; everybody's are different.
As I said above, everybody can do what they want with their body, but they can't force me to support them or continue a relationship with them.
In my sister's case she has lots of friends so I'm sure she's fine, and you needn't feel sorry for my parents - they would like us to be closer, but I'm very close to my brother so they get to see us together and all the young grandkids, so they're happy.
