I was not going to invite my oldest brother to my wedding. It has never been my plan to invite him. 

He is 20 years older than me and lives in a different state. We have no relationship - he was out of the house by the time I was born and then moved across the country and then when he came back to the east coast he was still 5+ hours away. We never talk. We aren't even Facebook friends. I see him maybe once every 2-3 years if he shows up at my mom's on a holiday (which he only does if his football team is in town and he can catch a game while he's here). 

He's also a dick. He lives for trolling and antagonizing people and insulting them, and he thinks it's hilarious. He finds excuses to make everything political because he likes getting into arguments. The few occasions I \*do\* see him, I would much rather not. I don't like who he is as a person.

Well my mom asked if I was inviting him and when I said "no" she threw a giant guilt trip. I explained my reasoning and she said she was disappointed in me that I couldn't do this for her. "I just really wanted an opportunity to see all of my children together." (Idk why she can't make her own opportunity. Like on Mother's Day. Or her birthday. Or literally any day other than my wedding).

So I told her "I will invite him if it is that important to you, but if he gets political or starts an argument or offends me or any of my guests even if he 'doesn't mean to' or 'is just joking', he is being told to leave immediately and you need to back me up on that. And if you don't, I'll ask you to leave too." 

She hasn't responded but my close brother thinks it was unnecessary to put that responsibility on her and that I'm being an ass about it. I think that if she "knows" my oldest brother won't be a problem then it shouldn't be an issue to agree to my terms.

AITA
