> "People with a rare genetic defect that adds abnormal features to their body is proof of the existence of a fake identity

No. You're the one talking about a fake identity. OP is talking about a whole class of people who clearly exist, not existing.

> mentally ill people believing they can decide to be something they are not"

That's a different issue. It is an issue.

> Jeff, I mean this in the nicest way possible, but "intersex people are transgenders" is a trap to get midwits to defend something that doesn't make sense by distracting them with technicalities so they miss the overall picture.

The overall picture involves details. Intersex is a modern concept that is probably not going to stick, just like most of how we think about gender, as gene expression and epigenetics tells us more and more about how our bodies work.

And we aren't going to get very far if we ignore reality that there are kids born that any rational observer is going to call trans.
