(Note: He uses the term “liberalism,” but I feel the more accurate term is “leftism.” “Liberalism” simply refers to the philosophy of individual freedom. “Libertarianism” is a form of “liberalism.” “Liberalism” is not the problem. “Leftism” is.)
He hates people because they are getting laid. He hates the women who are giving sex to the other guys, he hates the guys who are getting sex from these women, and because of that, he needs to go out and do violence to strangers.
That is every conversation with a Democrat I ever had, ever conversation with a leftist that I ever had. It's "I hate you because you have good shit. I hate that your life is going good, and that it is going better than mine, and therefore, I need to destroy you. I need to ruin all this good [bleep] because I hate my [bleep]ing life!"
That is what we see from the left in perpetuity: because they don't like good [bleep] in this world!
