"phallocentric" is this like when flatworms swordfight and the loser gets pregnant
Here's a tricky one. The online far-right absolutely can't remain silent at this moment. Like a shark, they have to keep posting or they'll die. And since they're getting paid to post, all the more so. But they can't risk really offending either party. So how to square the circle... I got it!

Ooooh, yknow, I have been assuming these flatworms were the New Guinea snail eater ones, Platydemus, but I forgot there are some European springtail eater ones, Rhyncodemus. these might actually be those. I don't know if that's better or worse

This is a real mating behavior in many species of simultaneous hermaphroditic marine flatworms (polyclad flatworms, such as those in the genus Pseudobiceros).
