I agree you can just leave but it also feels awkward as another guy mentioned. I'm not looking to cause drama and I don't even make any mention out of it if there's something I don't like there I just leave it and that's it. This is more of a "Silently not join the party with the person you don't get along with" so there can't really be any harm done like this.
I also realize that just because I can't get along with someone doesn't mean others can't too. I'm not talking about blacklisting or getting people kicked or trash talking. I'm just looking for a silent and non-awkward way to just not join something they are in.
