Yeah, that 0.4% of the population that are trans and the half of that percent that might visit the womans shower the same day and time you do, we need a law that forces someone that likely looks more like a woman than a man, who very likely doesn't want you seeing their junk any more than you want them seeing yours, in the mens locker room. You know- so you arn't offended at the gym in that extremely unlikely scenario strawman you've made in your head. Chances are you'll never share a locker room with a trans individual, but if you did I doubt you'd even know.
