I feel that if people genuinely love you, they accept you despite any differences you might have. So perhaps these people, despite what they claim, are not able to get past something that is within them to fully accept you.

I have been friends with people of other religions, other political orientations, other cultures. It's so important to understand that not everyone is the same and we don't have to share the same beliefs and opinions. It sounds like these people you're talking about don't understand this. I am sorry that it is so painful. It's okay to walk away from people who are not healthy or accepting of you.
