Yeah, I get it. Here's the thing though, this specific part:

I also have autism and some people with the condition aren’t as good as me at putting together the connotations of words AND the overall post to figure out the poster’s intentions. And some people aren’t terminally online and have less exposure to seeing this word used. They’ve likely overwhelmingly seen it used as a pejorative, and end up very skeptical of this post.

Those people all have one thing in common: nobody put a gun to their head and said "what's going on with this post? Make the call and post your comment NOW". One thing all we here on the internet do all have in common is the ability to read, and to use our sapience to make decisions about what we read. To say "this seems out of line. Could it be what I think it is, or am I assuming?" By process of elimination, a person either chooses to do that, or chooses to be assumptive. And also:

I don’t like the idea that people like me, or that people who might have reasonably arrived at a different conclusion about this, are being told that they’re huge dorks who need to go outside.

There is no reasonable way to get to the wrong conclusion.
Ever.
If you're being reasonable, you either find the right conclusion beyond all reasonable doubt, or you concede that you don't have enough information and then move on with your life. The only way to get to the wrong conclusion is to jump to conclusions, because being reasonable requires you to start from the point of "there may be no answer I can find". The people in this thread who got it wrong made assumptions, jumped to conclusions, and defended themselves by being belligerent. That is a fundamental lack of respect for others' intelligence that goes beyond being rude to people and using mean words.
