exactly right.

In todays climate, sex does not equal gender. I'm surprised that some folks are feeling the need to force a label with a rigid definition on things, especially the folks that are doing it. But that is what's happening. I'm happy with folks doing their thing and being whoever they are or want to be.

But I don't think folks should try to make gender (a choice) = sex (scientifically, not really a choice except in the rarest of circumstances). Even with reassignment surgery, the underlying genetics haven't changed.

And I'll add that in my opinion, most of the time using gender and sex interchangeably, is not a problem, but there are times when it could be vital to be clear and factually correct in the use of the words.
