Evidence of what?!?
The evidence is that this is caused not by a penis but by testosterone.
The dismissal of actual biological effects of a specific chemical on thought processes is insulting and uninformed.
Even if people exposed to testosterone train themselves to be on the look out for the effects, the effects and likelihood of slips on control of the behavior is still increased by the testosterone.
Stop telling women what we're allowed to be concerned by, stop telling us to ignore eons of history of abuse at the hands of males.
Also... this really ends up reading as if you're making excuses for rapists and men who commit sex crimes. It comes across as if you're saying "oh no, the rapist really is a good guy, he just couldn't handle the testosterone!"
The majority of men manage to go through life without sexually assaulting or raping any women at all. "Slips on control" seems like a really bad position to take.
If you want to pretend that the risk of pregnancy doesn't factor into the awfulness of what can happen at all, that's the only other scientifically validated fork here.
Sure sure, only the risk of pregnancy is scientific. The risk of physical and emotional harm, the absolute violation, that's all just imagined by women and doesn't count in your book?
It's kind of ridiculous that, even across the ancient world, people (including women) actually trusted eunuchs in spaces for females!
ROFL. Across the ancient world, eunuchs were largely BANISHED to spaces for females, because they were seen as less-than and not fully male - by which was meant not fully human. Because across the ancient world, females were viewed as the property of men, objects for men's use, and were excluded from the vast majority of social, economic, and political life.
While I'm not going to say there's zero risk of rape, I WOULD say the risk of rape from a eunuch is equal to the risk of rape from female (which is to say, it probably happens, but extremely rarely.
I would personally expect someone to have their testosterone managed before accepting them into spaces and sports for those whose testosterone has been (ostensibly) managed. Sperms in many ways provide a convenient cutout as a mechanism to close a loop on a number of corner and edge cases for sorting (such as high T females who still have a right to protect themselves from sperms), but this is only for private spaces, not for sports.
Well gee, it's nice that you have granted those high testosterone women the right to be protected from being raped. How very manly and magnanimous of your to allow this as a result of your manly views and manly decision-making.
The bigger issue comes in where some sports have actually decided on limits to testosterone which disqualify some people born without testicles... There needs to be some discussion on what, and whether some sports even need endogenous testosterone caps. I personally don't think they do as long as the requirements are such that those who have testicles either get them removed or take a suppressant to antagonize their endogenous testosterone.
Are you aware that women are not just "men without balls"? Seriously, are completely oblivious to the numerous physical differences between males and females? Please stop wishcasting.
I would much rather support an ID marker that identifies sperm-positive (really more "not sperm negative") and testosterone-positive statuses rather than "M" or "F", since this actually discusses biological realities rather than discussing bad proxies. In fact I would want this more just because I don't want it to be legal or even possible for someone to lie about whether they have been snipped or have sperms in the first place. I've seen a few people lie about that blatantly, and I think trust should not be a part of that equation.
In your world, there are men - virile men rife with testosterone... and then there is "everyone else". Apparently women don't get to be their own half of the fucking species, they're nothing more than failed men.
For those who are S- and T-, then there is really no argument against their inclusion into a space. For those who would falsify their ID I have zero compunctions against "Trueing it up". Which is to say, I have no problem with the government castrating those who lie about having been castrated, and I have no issue or complaint on giving vasectomies to those who lie about infertility.
People are not going to castrate themselves and adopt a female persona to feel "powerful". It's simply not going to happen. Or at least it won't happen at any higher instance rate than females who install hidden cameras in bathrooms because they themselves are predators.
The fact that you are so completely oblivious to your rampant patriarchal position, your premise of male as the cornerstone, and of "not fully male" as the sole characteristics of "other" is mind-boggling.
Honestly, you're the guy yelling "All Lives Matter" and bringing in so many arguments for why it's okay that black men are disproportionately targeted by the police, and why because it happens to some white guys too there's not a problem.
