As I was discussing with someone in the wake of some of the recent outrage outpourings, the cliff that comedy skirts has become very steep and very public. The joke that bombed in a small nightclub and gets quietly excised from the routine is now all over YouTube and Twitter, perhaps completely out of context.
Or a stupid dongle joke of the sort that I might have rolled my eyes at a coworker making and maybe told them to "give it a rest" years ago now gets people fired because of online outrage.
When someone is sarcastic or uses satire on you, you should take it as a complement, as it means they believe you have the intellectual capacity to grasp the joke, enough to take the risk in telling it to you.
When you respond with sarcasm or satire of your own, it confirms to them that you have found common ground, and that your satire/sarcasm can slowly lift into even higher levels of wit, almost trying to outdo each other.
When someone doesn’t get my satirical jokes, I write them off as a simpleton and use only small, safe jokes with them, if at all.
If you are going to make a sarcastic joke publicly, it is best to also make sure there is some sort of external approval in the form of laughing or upvotes to go along with it, otherwise it can easily be misinterpreted as your own serious opinion.
Maybe they go away thinking you're the simpleton for saying something which isn't true or doesn't make any sense? It seems like this is a whole system of snideness designed to judge people and justify being condescending to them. I think it's just unpleasant.
