Be sure to read the rule before you leave

I have seen plenty of times Lemmygrad communists trivializing mental illness.

I've not seen such, but obviously could have missed it or interpreted differently, don't read absolutely everything. In any case, communists are supposed to look out for the most marginalized or they are failing on a basic level of the ideology. And the most marginalized includes those with disabilities.

My read of the meme is just that sometimes people have takes that box people into positions where, if they acted upon them literally and uncritically, would make it difficult to do anything as an ideology; and the takes can exploit the fact that people in "left" circles do tend to be empathetic and genuinely want to be doing the right thing and helping people. And some of it is probably a psyop some of the time, whether actual alphabet agencies or "I'm totally one of you for real" rightists.

But there is also a certain amount of misinterpretation that goes on in it, I think. Sometimes a person who is "left" makes a point, such as about a certain use of language, so that people are more aware and will think about it, not as a prescriptive rule that you must follow at all times or you aren't a real "leftist". And then people will take it like it is a rule and say it's impossible to follow that rule and dismiss the whole analysis behind it.

Anyway, twitter is infamous for the "take that sounds like a psyop" thing. Though some of it may just be character limit woes, or people figuring that if they word something more provocatively, it will get attention.
