Good on you, but I think you're being a tad disingenuous in trying to paint this as anything but a leftist movement. I realize that you were only commenting on people here(and I'm not sure how accurate that is), but it feels like a framing of leftists in general not being for this, when they clearly are. They're the ones screaming that "Trans Women Are Women", and calling women "TERFS", merely because they don't want men in their spaces. They're the ones getting shit like this done, and not the 0.5 percent of trans people, who would be ignored if not for legions of leftists supporting this lunacy.
All that said, if you're against this, then you're not for wholesale "trans rights", and to them, you're no different than the MAGA crowd you criticize, for acknowledging obvious issues with this absurd movement.
