There is no set of "normal" things that a large majority of people all share. You can do things you consider normal without being a defensive asshole about it when it negatively affects somebody else (and vice versa, but I'm responding to you, not the OP).

> For me the point is that if you feel uncomfortable over something that is widespread and considered normal social etiquette, it's on you to deal with feeling uncomfortable, and you can't really expect everyone else to change their behaviour just for you.

Ah, the classic "fuck the neurodivergent" stance.
