No fanatic can be reasonable. Of any ilk. Fags. Druggies. Commies. Etc. They're committed verging on insanity. Actually, any of the above issues involving liberals already cross the line into insanity.

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.
