Because a liberal troll that baits as an agenda is not worthy of discussion. He said someone is talking about replacing Trump at the convention. He knows it is a lie and he is just baiting for a response. When called on it, and asked for proof of what he said, he does a Michael Jackson moonwalk.

On top of that, he replies to his own comments. Oh, there might be one other liberal that might also get involved, but generally, this is just an immature poster looking for attention, like a petulant child.
