Always refreshing to get someone who responds civilly and intelligently. I appreciate it! I do think you're creating a bit of a strawman there, but if you were merely pointing out the dichotomy of the argument in general then my bad.
The fact is that we have, I believe, 72 'genders' listed per my latest brief internet search on the matter. That is...a lot for a species with only two sexes. I'm all for ensuring we don't suppress individuality and enabling psychiatry and medicine to support people in whatever way best helps them. Again, the 1950's were not exactly the best of times for gender equality or understanding. But I do think we're playing with fire by working so hard to separate gender from sex; it's not that there is no room for depth to the topic of gender, but I really feel that we're crushing the wiggle-room of personality and thereby causing identity and confidence crises across society, especially in kiddos.
Just my $0.02 and response to you. It's definitely an important topic for discussion.
