I think part is maintaing ones cool under their blind ignorance. Yelling, shouting and insults is their forte but truth doesn't lie. Why guys like Ben shapiro, Alex Jones, Ann Coulter and on and on frequently DESTROY leftists in rational debates until the leftist just yells racism or some other slur and walks away, to the point of having to ban conservative speech on college campuses as the embarrassment just gets too bad.
To use this board as a microcosm, invite liberals here, have a rational debate, break them down, don't get into calling them idiots or morons as thats how they win, "See the angry name calling Conservatives". Their policies alone are undefendable and will collapse.
