I feel like "masking" is being used for "be polite". I didn't decide to be rude, I decided not to mask my disability.
That is bullshit.
People on the spectrum may have a harder time understanding what is rude, and that may give some passes when you don't realize it. But if you decide to ignore what you've learned is rude, you're just an ass.
And "going to bathroom and not pissing on the floor" is physical labor. Even more so if you are on crutches.
I completely disagree with your artificial distinction between "being respectful to others" and "politeness". Politeness is defined as being respectful to others
We all benefit from a more polite interaction. To refuse to be polite because it requires effort is just taking advantage of the system without paying it back.
Sometimes, you know it’s wrong, at least at some level, but are so fucking tired of masking all the time you just do it anyway.
