I don't understand this regression to the binary.
Your social media tools allow you to block content. I use this feature on youtube all the time. If I see a channel that's posting garbage or propaganda or flat out lies I just click the three dots and say 'Don't Recommend Channel.'
My youtube feed is a pleasant experience every day. There's no CNN or Fox news, no yelling talking heads trying to convince each other in existential terms, no jingoistic propaganda trying to influence me.
It's like what it was meant to be 20 years ago. Why do people not do this?
Your approach (which I share) requires thought and discernment, which is a scarce resource nowadays. People intend to turn their brains off when they doomscroll. (I'll never understand the desire.)
Instead, argue as if you're trying to convince the bored reader who has climbed down through the comments (for some reason), who has found value in this discourse and is trying to get more or better perspectives. That is someone you can convince of your position.
It's been a lot easier to engage in text discourse ever since I had that epiphany, because instead of taking every bait and trying to correct every wrong, I'm only engaging with folks arguing with data, with perspective, with good faith more often than not. That leads to better outcomes, I believe, instead of just contributing to so much noise.
