Give them an outside porta potty and tell them to enjoy their alone time.
No one deserves “special” rights. the idea was all were supposed to be equal before the law. Obviously, some are more equal. In a truly free society, I would guess someone could be a cross dresser. In theory, if that is all you are doing, it doesn’t hurt anyone (not that I personally think it is right). I think bathrooms are another issue as there is a chance of harm.
Aren’t they in fact arguing that to not allow transsexuals, (in the science community there is no gender, only sex. Farmers don’t gender eggs, they sex them. There is no gender reproduction, only sexual. And while I am on science, the whole xy xx chromosome thing has been “settled science” for a long time.) is harmful to the transsexual? Why is harm to them more of an issue than harm to you or me? Why must we change? Why must we be bilingual to get the job and not the laborer or the migrant worker? Will I be free to not cater to transsexuals? Why is a gun held to our heads to accommodate these people? And it literally is a gun. If we do not comply, the enforcement becomes more and more strict and if we do no comply law enforcement will take you away, and if you refuse to comply then they will do whatever they need to do to take you away, even if it is feet first.
