I disagree completely. You’re not. It’s not even being a brat. The family wasn’t truly welcoming. They wouldn’t stop pushing and prodding. You had boundaries and you acted on them accordingly.

By all rights, we appear to have differing political points of view but I would never let that get in the way of a holiday. Controversial topics and discussing opposing viewpoints can be fine if the conversation is truly in good faith. But it sounds like it was more of an own the libs thing. And it probably isn’t a good idea for the first time meeting someone, anyway. The family who can’t contain their toxicity even for the duration of the Christmas family gathering is the collective A.

And love him or not, I don’t know if that’s sustainable long term. Hating your life every time you see your significant other’s family is no way to go through life.
