I think they're trying to say "it doesn't matter what's in their pants" and that "anyone that associates genitals with gender is a bigot", but in a very haughty way.
Yeah, it kind of comes across as admitting that gender is biological. If the left can meme, they sure hide their power level well.
I'm gonna drop some sick hate speech while I'm legally allowed:
"Stop sexualizing children"
Fuck, police are here, brb
This confuses me because I thought it doesn't matter what is in your pants?
