Do seahorses do anything odd other than have the female give the father her eggs to carry? That's more like a mom leaving the kids with the father than anything that could possibly ever be used as "evidence" that males are interchangeable with females. Clownfish fit this BS narative more than anything I've ever heard about seahorses

Well, while these trans-fanatics aren't actual clownfish, they sure have the "clown" part down, anyway...

A youtube channel (I think minute earth?) proved that humans are more closely related to fish than sharks, sort of proving that we are "fish" if you define fish in a kinda incorrect way. So, from a certain point of view, they're also fish. Now they just need to find a way to go from clown fish to clownfish so they can finally prove that they're actually a different sex than their "assigned" one

Its based on using cladistic definitions. All tetrapods (mammals, reptiles, ampibians) are members of the Sarcopterygii clade, 'lobe finned fish'.

Lobe finned fish are all members of Ostiechthyes, 'bony fish', a group which includes most types of fish.

Sharks however are members of Chondrichthyes, 'cartilaginous fish'.

Both the bony and cartilaginous fish are members of Gnathostomata, 'jawed vertebrates'.

With a group like mammals, there's a last common ancestor where you can say that everything descended from it is a mammal. But with fish, there's no last common ancestor that would include everything we think of as a 'fish' without also including all tetrapods.

It's all because fish split into bony and cartilaginous subgroups first, then the bony fish had a branch where some of them gained lungs and became every land vertabrate. So since fish was sort of the "default," we have this unusual situation where there is no evolutionary branch that contains every modern fish and nothing else, unless we want to redefine cartilaginous animals
