we've definitely done it, too, here in the U.S., I know for example in North Carolina there was one program that sterilized almost 8000 people from the late 20s to the mid 70s, including people as young as 10 !!! eugenics was real popular outwardly here for a while, then after WWII they kept at this shit, they were just more quiet about it.They did state sanctioned sterilization on people here in Canada up until 1973, as part of a eugenics program. Mostly targeted at the mentally disabled, but a lot of natives got labeled just that over the years.
A fucked up part of our heritage.
