Or if a kid wanted to compete in the Westminster Dog Show would liberals support that too? "He identifies as a purebred poodle, he has a right to compete!"
That poodle obviously has issues. I imagine the owners do as well.
Actually trans-speciism might have its benefits. If you claim to be a dog, not only can you pee on the sidewalks, but you wouldn’t have to fill out a 1040.
