Propaganda frameworks like the one you’ve absorbed often include redefining common words and concepts in ways that support the desired conclusions

an influx of spammy low effort comments

deliberately trying to irk the mods and the community as a whole

Edit 2: Actually, I can tell you exactly what happens when someone comes in and makes this kind of "spammy low effort" attempt at talking about the Uyghurs on lemmy.ml, because I've done it. I spent about half a day talking back and forth with someone who was very, very insistently insisting to me that there was no genocide in Xinjiang, and the UN had proved it. To their credit, nobody removed anything I had to say, which I was a little surprised by. The post was deleted by its creator some time later, so I can't link to it, which is a shame because the whole exchange was pretty lengthy and interesting, and apparently consenting on both sides. I'll take out a random excerpt of the whole conversation here:

I asked, “Can you link me to the UN report where they found there was no genocide, and the so-called victims were millionaires?” You sent me a report. It doesn’t say there was no genocide, and it doesn’t say the so-called victims were millionaires. I realize you’re saying that a reasonable person can read the report and conclude that obviously there is no genocide at all, but I don’t completely agree with that. I’m allowed to not agree with you. That’s not “fighting.”

I’m really not trying to be hard to talk to or get you riled up. What you describe as “fighting” or refusing to absorb the information you are providing, I view as just healthy skepticism. If you run way, way ahead of your sources by painting a huge picture, you are completely correct that I’m going to refuse to become passive and let you educate me and believe everything you say. I’m going to take a step back and say, “Well, okay, I get what you’re saying, but what is your backing?” I can do that even if I’m not that familiar with the topic. The fact that you’re so upset that I’m not just believing everything you say is weird to me.

Edit: Also, this part deserves a real response:

Go speak truth to power on the streets, the Lemmy.ml mods aren’t “the power”, just some random people running their own instance.

Very true. I also think participating on the internet is probably not helping much of anything, in the current crisis, in comparison with actually getting out and doing something.

But still, if we are going to talk about internet stuff, big actions start from little actions. The same people who are swearing that they understand the way to make real progress, and everything needs to be reorganized to match their theories in order to fix the world, have in my view already gone askew and started abusing the tiny amount of power they currently have, and created a little "The Sims" version of a dystopian world which I want no part of. I think that's relevant to point out. And, which theory we're going to use and how we're all going to understand the world, including how we talk about it on the internet, absolutely has power in the real world in the aggregate. C.f. this most recent US election.
