If I wanted 24/7 Hitler fapping I would turn on the History Channel, good Lord.
I mean, if you want to try something like this, you gotta commit to it. If it's obviously sarcastic, it will just get you in more trouble. People will see that you're making fun and get angrier than they would if you just were quietly white, straight, and male. You can't just say "oh, I'm totes Jewish lmao" you gotta join a synagogue or something, volunteer with their Brotherhood, don't go around talking about your Christmas dinner. Even then, ask anyone who married into a Jewish family, if you don't look the part, people may give you a hard time if you don't work hard to overcompensate.
Going for enby is probably the most low effort but even there you have to commit somehow, get the dumb X on your papers or whatever, if it's too obvious you are taking the piss it will just make the whole strategy nonviable for anyone. Or if you are lucky enough to have some significant fragment of something or other turn up in your 23 and me results, glom onto that, maybe change your middle name to something culturally significant, etc. But if you are going this route, again, you gotta go all the way.
