You did say

Kidding, of course.

but immediately followed it up with

If you want a white asshole, you can just express empathy for anyone not white, and one will appear 🤷🏻

which lead me to believe the joke part was unrelated to anal bleaching and the intended joke was Ha, aren't white supremesists stupid and annoying? which, yeah they are. The topic of white supremacy in and of itself is completely unrelated and shoehorned into the conversation though.

Saying "Kidding", making people think you aren't being serious that bleaching your anus is a white supremacist behavior, and then saying "White Supremists will show up if youre empathetic to a non-white" subverts that expectation and re-enforces the idea that you believe anal bleaching is white supremacist behavior.

If the joke was supposed to be set up in a way where you did not actually believe anus bleaching was white supremacist behavior, it was structured poorly. The first part where you said

Justh white supremacy stuff 🤷🏻

wasn't really even a joke. You weren't set up to say that and subvert expectations within the context. I'm sure such a joke couldve worked here, but the way it was executed was doomed to fail. Kind of like white supremacists.

A better reply I'm now thinking of is "naw, my shit is so solid it grunts "crab battle" on the way out".

I assure you otherwise. I got that super test gene(not bragging, I actually hate almost every aspect of it). I have thick hair in my ear that I wave to wax once every other month or it would drive me crazy.
