So, it looks like Maher said this garbage on his show, Real Time.
In the same episode, he had Republicans join his discussion.
Two out of three people discussing here are Republicans. Do those two (especially the woman) look like they fear Maher? Does Maher look like he wants to kill them? No.

So yes, what he said was tasteless and stupid. I really do wish the guy would shut up already. He not only makes us look bad, but he's made black people look bad twice now. But honestly, I don't think he meant is as more than a joke.
And if he was conservative, you all would agree.
