Oh also since we’re on a technicality forum. Trans hormones don’t necessarily cause permanent sterilization. Plenty of trans people have children

I was just pointing out that the evidence provided with the 25% number doesn't really speak to fertility, but rather all the possible ways of having children.
And if it did, it would probably be from something like pollution/climate change, not a tiny minority of trans people.
As for the danger, population collapse is often precipitous - and by the time you notice it, is very hard to roll back.
And it's not just our species impacted by the changes.
