Have you guys ever heard someone said something before and when you surface it, the person said, "No, I didnt." and then proceeds to attack you for being a accuser or something like that? Fuck, I had it just now, annoying shit.

I know, I might be wrong, but look, that person can be wrong too. Who is to say I'm sure 100% without concrete evidence? But hey even so, how can someone CONFIRM it. Fuck this delusional people man. Always think they are right without considering otherwise. Don't they have a brain? Fuck.

Anyways, I'm angry. Any advice to deal with this kind of people?

Why not just ignoring them or ignoring what they say?
I mean, it's your fault when you're getting angry.
Think they are all - I am not allowed to call them "faggots" so let's say - "idiots" and not worth your anger.
At least that's what I do and it works so far;)
