Eugenics. When you boil it down, it's advocating sterilising those who don't conform in their early years.
Between the thirties and seventies 60,000 young Swedish women were sterilised. A (Danish) friend's thesis was on the subject of eugenics in Denmark, and he found that many women were sterilised just because they were prostitutes. The current attack on non-conforming teenagers may present as being different, but it originates from the same attitude of forcing everyone to fit the social norms, and if they don't they'll be 'fixed'.
