Lol no it's not at all.
My rational is backed up by peer scientific research and evidence. That's not at all the same as flat earthers.

Forgive me if I’ve misunderstood what you wrote, but what I’m getting from your evidence is that there are very, very rare examples that disprove the rule that when you are born you are male or female.
As if determining sex is a minefield. I would say it is almost always very simple.
Which is not to say intersex people are not important. And not to discount gender dysphoria.
