Fuck, man, I can't say I disagree with your perspective here. Nor can I say it didn't make me reassess my approach to online spaces.
It's difficult seeing the online rhetoric of irl bullshit perpetuating and exacerbating very real problems and not feeling like you have to address the bullshit to ensure there's a reasonable counter. I'm not 100% sure if it was your point, but yeah, we just shouldn't take it seriously. It's not apathy, but leaving the bullshit to irrelevance. Engagement is the goal of trolls afterall...
And you know what? I think you're right in that the remedy is less about what we're against and more about building the future we want to see. Genuine human connection is a great vaccine for preventing the spread of bullshit.
