You are correct, but calling a commie bastard a commie bastard is much more satisfying sometimesYou aren't going to change the view of a diehard anti any more than that person will change yours. You are having the conversation for the benefit of other people reading the exchange many of whom may be on the fence. You are looking to influence THOSE people. So in that vein, avoid divisive political epithets (libtard or whatever). You win with the interested observers when you make good points and remain objective while your opponent devolves into screaming "nazi" or whatever. They win the moment "commie bastard" comes out of your keyboard.
