I could make a nice, long list (I'm pretty touchy) but here are a few of the worst:
Gaslighting/being invalidated: being told what I really feel/experience (contrary to my own statements), or having my behaviors/preferences retconned, by somebody who can't possibly know because they aren't me.
My appearance/having my picture taken. I don't share photos (or do video or voice chat) basically ever.
"Everyone is beautiful", "you don't need a relationship to be happy", and other glib, projective nonsense.
For forty-seven years I've put up with it now. I must stop Christmas from coming ... but how?
