If you're okay with screwing up 5 normal kids for every kid who might actually be gender dysphoric, you don't actually care about child welfare and will sacrifice as many of them as necessary to validate your ideology/lifestyle.
@ArdanianRight I actually did wanted to become a girl when I was little only because they get to cut in line ("ladies first") and they usually get their own bedrooms while the boys have to share. I got over it.
