Have they had the surgery, though? (Not that it matters, they're still a freaking jagoff) And even then, I don't think Blaire White has gotten the snip, but I'd a bunch rather share a bathroom with her than McKinnon. (Hell, I wouldn't want to share a bathroom with McKinnon even if they were a CIS woman. They're a bitch)
I don't think the bathroom is THAT big of a deal, because people can always pass. Remember Rose McGowan's girlfriend? She totally looked like a man, and I don't think she was even trans. And as seen it's not like it stops pervs from going in bathrooms to screw with people. (Little BOYS are still in danger in the mens' room)
Sports is the area that really concerns me. Otherwise, I don't give a shit, but the whole, "oh, it's no big deal", no. At the very LEAST, there needs to be a lot more study done. There IS a great difference, like it or not, or we wouldn't HAVE separate mens' and womens' leagues and competitions.
