There’s actually some useful information here if you ignore the hyperbole.
If you act like a jerk and are mean to people, you will drive people away from your causes, even if you are taking a position that is strongly defensible from a moral and ethical view. If you take the view that “I don’t have to do the emotional labor to educate you, OMG read some theory, you’re fucking stupid if you can’t understand this, you don’t deserve to live if you think Y,” etc. you aren’t going to win people over. And yes, if you are always acting like an asshole, you’re probably going to drive people away that believe similarly to you, because they won’t want to be associated with assholes. That’s human nature, and something that you need to learn to contend with if you want to win adherents to any political or social position.
In other words: leftists and feminists, fucking get over yourselves.. You may not want to put in the emotional labor because it’s exhausting, but you know who will? Fascists, nationalists, misogynists, and religious fundamentalists. If you just want to make fun of and vent at people on the right, you’re only creating a more insular group that more and more people are going to end up hating. See also: hexbear,
