I think that does change things.

I was previously inclined towards something like, “He’s your brother, and I would try and say to him that while you disagree with him as fully as it’s possible to, you will still be there because he’s your brother, and that still means something to you” or similar. Something that might get him to understand that this isn’t easy for you.

However, if you were already at his actual wedding, and this is just a party in another country, nah - tbh, I think it’d be fair to give it a miss even if he wasn’t being a Nazi apologist.
