You might have pre-empted this but the objection I am going to have here is that the people who opposed rights for black people would make the same arguments. That there is something intrinsic about being scared of another race. And I don't think you have shown there is a real difference. If people had grown up changing in front of people of both genders there wouldn't be a societal issue with changing in front of both genders. It's instinctive to fear other races... but it's not right. It's instinctive to fear other genitals.. but it's not right. Could be?
Certainly fear of other races is extremely common, and may very well be instinctive. That's a complicated issue. In my opinion, and I suspect in yours as well, society is not well served to pander to those instincts, or to enshrine them into law.
When it comes to the fear of other genders, I personally think it is not only instinctive, but rational, for all the reasons stated over and over again. I think that there is a reason that we do not change in front of both genders, except in very controlled circumstances, and I don't think it is just societal influence that causes it. However, be that as it may, that isn't the actual issue involved here. Once again, if you want to argue that there should be no segregation of changing facilities, or come to think of it why should there be changing facilities at all? Why would we go behind a door to change clothes? If that's what you want to propose, then the problem is solved.
However, if you want to maintain a locker room for men and a locker room for women, that's a different story. That's what we have here. I can't understand any way that you can logically assert that I, a cis-man, should be excluded from the women's locker room, while some other male bodied person who declares himself to be a transwoman should be allowed, unless you are willing to simply ignore the wishes of the cis-women who object.
You have to use the women's locker rooms then cos you're a bitch boy cuck. You don't mind do you. I mean you can still watch Rambo and wear pants.
Please Bre'r Fox, don't throw me into the briar patch........but in this case I think the people sharing the locker room would object.
Oh....and....I see you've descended into illogical name calling, emotional appeals, and the stuff the makes for lofty rhetoric, but not actual meaningful dialog. By all means, demand freedom and rights for everyone! Privacy rights aren't real rights anyway.
