Ok. You don't believe them.

Good for you.

Why should anyone else care what you believe or not?

And why would they bother lying, when they can just... not? They've been clear about who they are and what they're doing from the start. The "I say what I want" crowd can't say what they want there, and if they keep having y'all show up and try and ignore the rules, then why wouldn't they just get rid of you all at once?

You're trying to claim conspiracy as to why you've been dis-invited from the party, when the reality is they just realized they didn't want you there.
