I also work in accessibility field and what you say sounds very unprofessional.
If some website or another product uses ascii graphics or emojis to show important information, then yes, this is something that should be reported and if this is the company which hired you as a specialist you can affect and they should fix it.
But telling people that you hate them just for the fact that they upload ascii pics to their personal feed is the same if I tell publicly something like “Hey girls! Stop wearing nice dresses because I don’t see them!”
Sounds strange, doesn’t it?

If someone who knows you sends you such content then of course you have a right to argue and ask for something different.
But you have no right to hate everyone just for the fact that he/she doesn’t care about your comfort.
Then I should hate my friends who share photos without alt texts?
Or should I hate people with nicknames like n1ntend0 (which means nintendo)?
Of course no.
