They were obviously baiting her to argue and demean her. Normal families don’t talk politics at Christmas unless they are trying to pick fights. I think you and your family need therapy.

Just because you’re okay with how your family acts like that does not mean it’s okay for his family to treat her like that.

Wow, sounds like your family is as effed up as his. She had every right to leave and glad that she did. Dump his ass and find someone better.
