If you don't want trans women, get ready for big, hairy, deep voiced, muscular trans men in your ladies rooms. I assure you we can make you feel even more uncomfortable in your "single sex" spaces, and we will make an absolute point of doing so.
Well, I feel pity for all the sniveling ladies shaking in their restroom stalls at the terrifying idea that maybe, one day, an unseen penis might exist in the same room as them without them knowing. If that's womanhood (and it's not), everyone should transition.
