It doesn't matter if it's the law or even if it's YMCA policy. The expectation is if you go into a locker room that is clearly marked "Women" that you will be in a room with other women. That's a reasonable expectation. Why should Rosey change her gym just because a Trans feels like a woman and wants to use the women's locker room? That's taking away Rosey's rights in favor of another group of people.
You're confused... you keep talking about "rights" but we're talking about a private business's policy.
Let me see if I can explain using a different company. Chic-Fil-A openly donates to anti-gay organizations. I disagree with that policy, so I don't spend my money there. By your logic, they're denying me the right to eat their food, so they shouldn't be allowed to support those organizations.
If they have male parts they are male. If they have female parts they are female. That's a scientific fact too.
Except that it's not black and white like that. An estimated 1 in 1500 babies are born each year where the doctors can't determine their gender:
The percentage would be higher if you consider anomalies that only show up when the child gets older (like a male developing breasts at puberty).
1 in 1,666 births have neither XX nor XY chromosomes, and 1 in 1,000 have XXY chromosomes.
Late onset adrenal hyperplasia (like an apparent female producing male hormones at puberty, or vice versa) occurs in 1 in 66 children.
And 1 in 100 people have bodies that physically differ from male or female.
There are several other traits that contribute towards being intersex.
I never said anything changing or adding any laws. To me it's very simple if you have male parts you use the male lockers, if you have female parts you use the female locker room.
OK, so how do you define male or female "parts?"
How about a teenager with a penis and breasts? What if it's a very, very small penis?
Or a teenager with a v*gina, no breasts, but a hairy chest and beginning of a beard?
How about those 1 in 1500 babies that were born with no discerning genitalia, so the parents and doctors chose to do a surgery to make them more "normal?" With 70,000 people in Wilkes, this describes 46 people in our county.
Do you think the YMCA should inspect everyone's genitalia before allowing them to use the locker room?
How about a butchy lesbian with a short haircut and a wife-beater tank top that keeps licking her lips while openly watching Rosy change? Would you agree that anyone that appears to be gay or a pedophile should be forced to use a different locker room, too?
Personally, I'm uncomfortable with any stranger watching me change clothes. And if I had a kid with me, I would be extremely uncomfortable with a stranger watching them change clothes. This is why I go to Anytime Fitness... they have several unisex bathrooms, but only one person at a time. But most of the time I just show up in my gym clothes, work out, then go home and take a shower in the privacy of my own home.
Rosey has a right to use a locker room as it has been designated not as someone wants to feel it should be used. Unless you agree you are accommodating the Trans over Rosey and taking away her rights in favor of the Trans..
But that's just it... she doesn't have that "right" because there's no law on it. The only right she has is to choose whether or not to use the YMCA.
And if she did have that right (which, again, she does not), then the YMCA has chosen to designate the locker rooms as open to transgender, which means that both she and the transgender "have the right to use the locker room as it has been designated, not as someone (in this case, you and Rosy) wants to feel it should be used."
Personally, I tend to argue in favor of less government, and allowing businesses to set their own policies on most issues. If enough people agree with Rosy and stop using the Y because of this policy, maybe they'll make the investment to build private unisex locker rooms and restrooms.
