I think you’ve made a number of extrapolations from the other commenter’s post, that I don’t see them having said.
I understood their take to mean: abolition doesn’t work (as we’ve seen repeatedly in history). You can’t make something disappear just because you don’t want it to exist. That doesn’t mean “do nothing”, it means take a realistic approach that will actually make a difference.
I want to be clear - I’m with you. There’s a lot of things that I wish never existed but in lieu of that - I am learning how to navigate a world with powerful technologies in the hands of bad and powerful people - and being an agent for change without killing myself in the process. The commenter was being empathetic, suggesting you may want to take an approach that won’t exhaust yourself. This person is an ally - and you are going to fail if you can’t recognize that.
That’s messed up. A teacher should’ve shut that down.
