There's a difference between "not everyone gets the joke" and "you're the only one laughing about your jokes". Think about bullying. Would you say the problem with bullying is that the bullied doesn't get the joke?
Humor can be used/misused for all sorts of things. Some bosses at work use humor for power play. "Incels" use memes to spread misogyny. Or remember the old-timey caricatures of Black people, Jewish people, Asians... you name it.
And the problem here is: On the one hand you act like you're well up to so many important issues that everyone else was too numb to see. But at the same time you display such ignorance when it comes to your own responsibility. And no, I'm not saying your posts discriminate against anybody. But when you feel like people have to read a wikipedia article to get your joke, I think you got the wrong idea about what this thread is.
