This doesn't seem drastically different than what was openly happening to Native Americans in the US until the passage of the Indian Child Welfare Act in 1978. By some estimates, as many as 3/4ths of Native American children were taken from their families for adoption or foster care. And that's assuming the law stopped the practice, some states still see many Native American children shipped to non-Native communities…
Likewise, the Stolen Generation in Australia.
19th Century America was extremely anti-Catholic. Many immigrants from predominantly Catholic countries were treated as "not white" or "not white enough" and discriminated against.
