You think people shoulder cater to your needs and respect what you want, so maybe transgenders who are MTF or FTM but don't actually look like it should respect how uncomfortable it may be for people when someone strolls in a females washroom but looks 100% like a male or the other way around. It's not because they hate you or think you shouldn't be trans it's just human instinct that it makes them uncomfortable.
If someone doesn't like seeing you in the washroom, they still won't like it either when it becomes legal so you may as well just not care and do whatever because they will dislike it either way.
