Well, there it is. I was always assuming this conversation would end with me blocking you because you said something so creepy or mysogynistic or disingenuous that I just couldn't handle my disgust anymore. Your cult-like ideological brainwashing wasn't really in the running.
But yep, there's no point in talking to somebody who can say something this stupid. You're clearly not interested in good-faith conversation at all, and will cling to your nonsense no matter what insane bullshit you have to say in order to do so.
Human beings can tell whether somebody is male or female, at a glance, with something like 99% accuracy. THREE MONTH OLD BABIES can do this (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6680589/). This includes the fact that in the overwhelming majority of cases (easily in the 90s), we can tell the sex of a trans person. This is the entire reason why the concept of "passing" exists.
The fact that intersex and androgynous people exist doesn't mean that there's "no way to tell" what sex somebody is. Cherry-picking one in a million sexual developmental abnormalities and then generalising them to the entire human race is just asinine.
I don't know what's happened to your brain. I don't know why you're so deep in this ideological mess that you are willing to deny reality. But honestly, I don't care anymore. You're not worth blocking, but I am going to put you on mute so I won't see anymore of your replies.
Good riddance.
