I’m openly curious how well a “liberal” minded individual who isn’t afraid to be an asshole would be received.
Speaking from experience here, people will actively, and sometimes collectively, attack you for it. They’ll gang up on you online. They’ll openly and often violently bully you in real life. They’ll even abuse the legal system to get rid of you if they are angry enough at you.
Being an asshole towards shitty people (and the vast majority of humans are shitty people, myself included) is very VERY enlightening on how our rights and our laws are just a thin veneer covering what really governs our lives, and that is our feelings. Most humans could give a fuck less about logic, facts or the truth; they only care about their emotions and what they want because they are only connected to the real world through their emotions, not their minds.
Humans are no better than base animals and being willing to be a horrifying House-level dick towards those you think are deserving demonstrates this, really handily.
It doesn’t surprise me that poor young man was forced to go to an alternate school where the diploma he’ll get won’t be as respected by the colleges he’ll apply to. He probably told them off for being so blatantly racist and, in their hurt, they kicked him out.
