About as many as say "It isn't a good idea to call your opponent a faggot" when they actually mean "I've already ceded that territory to the enemy; stop reminding me I'm a coward."
Take your pick as to whether the territory is homosexuality or name-calling.
So let me get this straight: People who think calling someone names doesn't make your point only think that way because they're cowards? What's brave (or cowardly for that matter) about calling someone a name?
