This is a very deliberate practice, especially amongst left-leaning shitheels on places like Facebook and Twitter. It's a sort of "refuge in audacity" thing. You see it in the posts from the
Translesbian Memes thread as well.
Hide behind so many layers of irony and act so ridiculous that no one can discern what's a serious thought, and if someone presses you on it act like they're stupid for not getting it to humiliate and ridicule them. Pretty frustrating tbh.
Edit: The solution is to just accept everything they say is absolute exceptionalism, btw.
