No fanatic can be reasonable. Gun control is one of the fundamental tenets of the religion of liberalism. When you disagree with this you're not really presenting an alternative point of view to be considered, but in the liberals' minds you're committing blasphemy. To them you are evil and must be destroyed.
Reminds me of a thread on FR recently concerning Al Bore's interview with a journalist and the journalist was asking for clarification on Bore's position. Instead of answering and reasoning, Bore dismissed the inquiry by asking, "Are you a denier?" The journalist repeated his question and Al dismissed all of it as a denier and walked off.
Liberals aren't just stupid and crazy, they're cowards.
