3. No, they aren't.  But they are allowing people who outwardly express gender characteristics ("live as a woman") to use the women's restroom.  You're the one trying to change that by instituting a bathroom use policy that relies on a biological definition of male/female that most people don't even know if they fit.  Have you had your chromosomes tested?  Do you know if you're an xx male? Do you know if you have vestigial ovaries from a development issue that technically make you intersex? If you have elevated estrogen levels?  I don't.
		
		
	 
Simple way to classify.  Someone stands there naked in front of a doctor.  Doctor examines them for a few seconds, then says Male or Female.  Real easy.
Stop making it ONLY about the transgender person.  It isn't, nor should it be.  It's about everyone else that is being told to #### off here.
If this wasn't a major problem for everyone else, there wouldn't be any separate bathrooms for males/females to begin with.
Maybe you should think about why those exist in the first place.  Chances are you havent, because every post you make is 100% about the transgender people and 0% I don't give a #### about everyone else.
