Should I host a nye party that I don't want to be there for?
Probably not. How are you getting out of it?
I'm going to tell them how much I hate them
Parties are fun but you don't have to have one if you don't want to. It will just make you unhappy and you will make others unhappy.
Why shouldn't everybody be unhappy?
Because what do you get out of everybody being unhappy. Just don't host but let people know so that they can make other plans. That way both groups will be happy.
