Terfous - you are indeed correct, but absolutely NO ewes have testicles 😉. If they did, they wouldn't be a ewe.... that's not to say that every sheep without testicles is a wee, they aren't, but there are absolutely no ewes with testicles, just as there are absolutely no women with penises.
But since biological facts are apparently transphobic it was only a matter of time before they anthropomorphised the argument onto animals.....
