The trigger warning is because the topic can be emotionally heavy for autistics since it talks about the social abuse autistics endure and how we react to it by masking. The guy has an apparent justifiably angry tone throughout the video. Otherwise, I think it is fine and there are no sensory issues to worry about.
For those that downvoted, I would like to know why. Why did you think that it should not be seen by others?
Unfortunately not so much, surrounded yourself with people that accept you for you and spend absolute minimum time with people that don’t.
Edit: Didn’t mean to dubble post, I’m having some internet problems.
