See, because the reality is that whatever you believe is true about sex and gender, cis passing is definitely on a spectrum.
For example, as I said, I pass well enough to go through a police patdown with no hint that I might not be a biological man - but I couldn't pass a strip search.
Now let me let you in on a little secret: This is why the best plan is to let people figure out what facilities they belong in, then enforce the rules or laws about appropriate behavior equally.
Vilified as self ID, this simple solution results in basically no issues. Trans people generally know where they're least likely to stand out. If they can't help standing out they know where they are safest.
Before the recent reactionary panic one focus of the trans rights movement was making sure there were safe options for all trans people.
This project is now ridiculed as having been too extreme. It never reached its goals of universal trans safety in public spaces.
It was never extreme for trans people to want to be treated like human beings in whatever spaces we entered. It did not go too far, and no amount of historical revisionism will make the simple request for equal access to safety in public spaces unreasonable.
And the spectrum continues from there. Some people pass 99 percent of the time. Some pass 90 percent. Some pass 60 percent. And ofc some cis people are mistakenly clocked as trans people.
The more passing is policed, the more cis people get clocked mistakenly. It's a spectrum, and you're on it too.
