This again seems to be a fundamental misunderstanding of what Self-ID laws mean and what is and isn't currently possible anyway. People don't get checked for gender when they enter the toilets right now.
You've brought this up several times. I can't decide if it's semantic tomfoolery and pretense... or if you genuinely are incapable of understanding this concept.
The current state doesn't check for gender when they enter toilets because
the vast majority of people are visually obvious as either male or female on a simple glance. There is no need to check ID, because if
a person who looks like a man enters the room, it is
socially acceptable and appropriate for women to challenge them and ask them to leave. If they refuse to leave, it is reasonable for women to involve the owners of the premises or the police (depending on venue), as it is
reasonable to assume that the opposite-sexed interloper is up to no good.
Self ID changes that current policy. Self-id replaces sex (which is almost always able to be determined by a cursory glance) with an
internal feeling which cannot be verified by anyone at all. If these laws get passed, it will mean that
any male who wishes to can enter the ladies toilet, whether he is trans or not. Furthermore, it means that it will
no longer be allowable for women to
challenge his presence in the toilet. All he needs to do is utter the magic words "I'm a woman" and he
cannot be asked to leave.
Yes, some transwomen currently use the women's rooms without challenge or complaint.
Most of those transwomen have made efforts to pass and most have undergone medical treatment to appear more like a female. Women accept them
out of politeness even though we can tell, and occasionally we cannot tell (although this is a lot more rare than you seem to think).
Self-id destroys that polite fiction. It allows any male to enter
without any expectation that he present as female in any way at all. Self-id robs women of the right to challenge the 6 ft lumberjack with a beard. We are
forced to accept any male who wishes to be there and no longer have any safeguards.

You're trying to change the rules, and then pointing to how things work under the old rules as proof that changing the rules is fine.
