Important context. Thanks

I'm pretty open about the fact that I have autism, and there have been a few times when I have used the strategy in these tweets, but adding the invocation of my autism.

When I ask them to explain why it's funny, they will often try to deflect the conversation at first, because they're uncomfortable at being challenged. I can then double down on asking them to explain the joke, being all apologetic and saying that jokes often go over my head because I'm autistic. That makes it much harder to deflect, especially because I'm super good at appearing earnest when I'm asking this, so it manoeuvres the joke-teller into a no-win situation, where they either explain the joke, and look like an asshole, or they don't explain it, and they still look like an asshole.

Then when they do eventually explain it, I am good at making my face fall in disappointment, before saying "oh, that's not a very funny joke". It gives me a great deal of satisfaction because there are many people who believe that autistic people are incapable of lying or acting, when in fact, being autistic means I've spent my entire life learning how to put on a performance for the outer world.

Sexist jokes or the likes

Racist/sexist/ableist/etc humor.

It took me a couple readings to catch the nervous laughter part since it isn't something I do myself.

I assume there’s context missing since it says “replying to”

So I assume they meant something like “my dad only told me xyz” or like “wow that’s nuts, my dad just said xyz, not all that” or something roughly along those lines.

"just" as "nothing more than [...]" - it was not much. "Just" a sentence or two. But it was enought.

The word "just" doesn't only refer to time.

"Then help me please, I want to participate, too!"

They mean when someone makes a joke in poor taste. Not actual funny things

Why do you assume the least charitable assumption? It's good advice in appropriate contexts

I think a lot of people just didn't understand the context. It maybe says something about the people I interact with regularly, but I haven't heard a sexist / racist / uncomfortable joke in person for years. Once I stopped hanging out with teenagers, it pretty much took care of itself.

Understanding the context, and knowing that lots of people have to spend time with assholes, i think it's good advice. But it isn't that surprising that, without any context, lots of people don't assume she's talking about a specific type of problematic joke, sincs there's not really anything in the text to suggest that. In which case it's pretty sociopathic advice.

Which ones? I'm not seeing that.

On the internet, you get people pretending to not understand things in every context as if walking around slackjawed and clueless talking about all the things they don't understand with some kind of aloof and detached attitude makes them better than everyone else. I think this post is talking about sexist jokes though, not that.
