It's part of the game, X.<quoted text>
I know you're lying. That's what I know. How can you go on and on about honor and hypocrisy and just outright lie about me? You're full of chit. That's "what I know".
Provoking by lying about a person is the best way to get a reaction and to anger someone. No one likes being lied about.
The difference here though is that these liars have no conscience, and they don't care that they're lying about others. They'll simply accuse you of doing what they're doing, and round and round and round it goes.
It's the reaction they want. Then they'll turn around and accuse you of making trouble or being off topic when they instigated it.
