Just because someone's an asshole now...
Just because someone's an asshole now doesn't mean they always were an asshole, or that they always will be one.
Don't hesitate to stab a bitch when needed, but also don't act like it's their entire existence's unchangeable fate to have your knife buried in them.
Confrontation - sometimes even violent, aggressive ones - is necessary, but being blinded by self-righteousness and justifying every swing, every punch, every bruise you make is how you become just another asshole in this rotten place.
This isn't even accounting for the cult-like indoctrination processes that radicalize people into committing horrifying hate crimes.
Also - it's dangerous to think that you are immune to hate propaganda, because "only assholes fall for it", and you are "not an asshole".
