No living being on this planet is weak or stupid for having a dysergulated nervous system as a result of trauma. Any serious materialist reading your post should understand how trauma responses form and get triggered instead of falling back on protestant brainworms where everything bad is a personal moral failure.

Ableism is a huge issue in society at large and leftist spaces are hardly any better than the average. People should make an effort to accomodate and at least meet you in the middle instead of putting all the pressure on you to pull yourself up by your mental bootstraps and ensure your trauma isn't too visible and annoying. Especially when the accomodation in question is as simple as being more careful with the choice of words in a written format where you can pause and review before posting.

Don't hesitate to stand up for yourself and make demands. If you don't feel comfortable pointing out the specific terminology you have an issue with publicly, you can message me and I will do my best to keep it in mind and avoid it. And if I am among the people who make you uncomfortable, feel free to call me out.
