I'm fan of dark humor, but guess what? It is increasingly hard to get away with displaying it these days. It is fraught with consequence if you display it in public, and social media is the town square writ large and everyone gets a megaphone and an eternal recording of what they say in that public space.
Do I like this fact? No. Do I dislike the fact that the end of the political spectrum that gave us this set of rules is saying people who agree with their politics should not be held equally accountable to the mob because those doing the complaining are from the other end of the political spectrum? Yes, and good. They should suffer with the fucking mess they have made.
You want to explore dark humor these days, paint a picture, write a book, make a movie, put it in some kind of container before you stick it in the public space. Going all performance art with your own identity is a bad plan.
People who don't understand that are either stupid, or they have something fucked up with their wiring that doesn't let them see the boundaries society is putting up. You don't want to invest in either of those groups, it's a bad plan.
A crucial part of humor is understanding your audience. You're not going to walk into a Catholic church and start making pedophile priest jokes so loud that everyone can hear you. People need to learn to treat social media as if they're out in public. If you have thousands, or millions, of followers maybe its not the best place to engage in graphically dark humor. It doesn't help that the Twitter format makes it hard to add context or tone to posts, so it leaves much up to the reader.
Mind you, the royally fucked political bullshit these days does make everything worse and has completely ruined social media.
