Excellent point. If you get bent with rage, the Left wins.
I have found that the best way I can mess with a Leftist during any argument is, when they (predictably) turn foul, I refuse to go the same route. It drives them up a wall when I keep the tone civil, and makes them get even more foul as they try to get me to respond in kind.
There’s a moron Leftist (I know, redundant) on Twitter who’s given up arguing with me because I refuse to join him in the gutter as I use facts to demolish his arguments.
I’ll convert him yet.
