Your post is spot on. I agree 100%.
As for those rare conditions, I never knew much about them before the uproar over that boxer in the Olympics. It turns out, many people born with those conditions never find out until they reach adolescence. So, for instance, they are raised as girls. When they don’t develop like most girls at puberty, the doctor runs tests and they discover they have a rare condition. It is devastating for them.

Years ago, there was no way to tell at birth what would happen at adolescence. With DNA testing, there should be almost no need for a mixup anymore.
