I just recall him calling you "Sway" and trying to get himself lynched so he could use his vengeful kill. It sounds like you're overreacting.
How would you like it if someone you don't even know starts talking to you about personal information in the middle of a mafia game? He's a creep. I'm hardly 'worked up' or 'overreacting', the guy is just a creep. That's just a fact. Not even mad about it anymore, just don't like him.
