And that's how misinformed movements backfire.

• A lot of AFAB people with XY chromosomes, who wouldn't have had problems until now, will now have problems going on with their daily lives, causing more childhood trauma and finally, more revenue to therapeutic drug manufacturers.
• History repeats: First "black" people didn't get toilets, now anyone whose chromosomes don't match their gender, won't get toilets.

Once they find out just how many people with mismatching chromosomes exist in the society, that have been able to live normally until now, things will get out of hand, once again.
And then the only ways to fix it would be:

1. Make a separate toilet for each and every gender classification
2. Have only unisex toilets

Guess which one is actually viable.

What will happen to sports? No idea, maybe someone can share their insights.
