When I get trolled by libs, the language is generally so foul it can make a longshoreman blush.
When I worked construction in my youth, because I didn’t swear, those around me noticed and stopped. Don’t think that is true today. There was an element of respect of others back then that doesn’t exist today?
I always offer up a thesaurus. So that they can enlarge their vocabulary. :-)
I never swear back. I’ve been hundreds of these debates. I wrote a whole page on it http://www.futurnamics.com/debaterules.php
You will NEVER win a debate with a foul mouthed liberal. So you have to remember your larger audience of onlookers is the real target. Just state your position clearly, calmly, and that will really enrage them.
If they call you a racist, always tell them they are the racist for supporting black baby abortions, etc.
I usually leave them in frothing hysterics.
