Again, the rendering issues were not my problem; I can read markdown well enough that it's not a true barrier to communication. The issue is that it is by no means clear what your point is. Even knowing that's what your message was, it's difficult to gain that information from the text of what you said. It's poorly structured and lacks a clear thesis. There's grammatical errors that make it almost impossible to parse. Some of the points seem totally random to include. Etc.
It's also just... not how a realistic idea of how a meme community works. Seldom do people have the original post to link back to, and posting purely in text is somewhat antithetical to the whole concept (if that was your suggestion, I'm still uncertain about that. What is "text alternative"?).
I really think that if this is important to you, you should go back and heavily rework your template so that it's clear to the reader what you mean.
That you misunderstood when I was quoting you should really be a sign here: I meant what is a text alternative; as in, can you give a more complete example of a text alternative. Just linking back to the source, especially ones that may not still exist like older screengrabs of twitter, is not a complete solution.
Also you seem to think OCR is for some reason a bad solution when afaik its never even been tried broadly on lemmy, and you dismiss both OCR and manual transcription as "bullshit" when both solutions enable all of the accessibility features you're (I think?) requesting (and they're also extremely commonly used by members of several-if-not-all of the groups you're speaking for). The assumption that everyone here is posting OC is also demonstrably just not the case, there's hundreds of hits for this screenshot alone that have the exact same size, ratio and cropping going back years.
Seriously your heart seems to be in the right place, but maybe you're a bit blind to the idea that some of the realities you're basing this on don't entirely reflect the one we all live in?
