This whole bathroom thing needs to come to a head (so to speak) ASAP on a nationwide level, so we can settle this BS once and for all.
Using ladies' bathroom table:
Present female? Look female? Vagina? Use bathroom?
NO NO NO NO
YES NO NO ?
NO NO YES ?
NO YES NO ?
YES YES NO ?
NO YES YES ?
YES NO YES ?
YES YES YES YES
We can't exactly check genitals at the door, so for argument's sake, we can wipe out that entire vagina column.
Present female? Look female? Use bathroom?
NO NO ?
YES NO ?
NO YES ?
YES YES ?
The fact is that you indeed CAN present female and look female without having the equipment, and nobody will ever be any the wiser and there are *big surprise* no problems. You can also have the equipment, be legally or cis female, but somehow your looks place you in doubt and you have issues. I have seen a butch lesbian get called out in a public bathroom before and a threat of calling police was issued.
Since all transpeople (and all people, for that matter) must be treated equally before the law, "passing" or not, and we won't be having bathroom police checking IDs and genitals, the only logical thing to do is have people use the bathroom they are most comfortable using, regardless of how they make others feel by merely existing.
I know I've oversimplified things for the sake of post length, but this is what these mouth breathers need to think about. After all, we really can't have FTMs in the mens' rooms either... /sarc
