It is true that some Native American children were removed from their homes on reservations and placed in schools. This was primarily in the late 19th century, lasting into the early 20th century. It should be noted that conditions on reservations were pretty horrible at the time, for a number of reasons. Reservations were established on the worst pieces of land, where farming and other types of production were all but impossible. The government tried to give aid to the Indian tribes, but corrupt officials often grabbed most of the money. By the late 19th century, extreme poverty, crime, and alcoholism were running rampant on most reservations. I’m not trying to make a blanket justification for government policies here, just saying that the situation is more complex than what your post suggests. In all modern countries the government has the authority to remove children from homes under certain conditions.
The effort doesn’t seem to have succeeded, does it?
You should probably put that website next to Stormfront on the list of online hate sites that aren’t trustworthy sources of information. The inaccuracies are quite obvious. Just starting from the bottom of the list, the claim that Catholic clergy took part in the Rwanda massacres is backed up by a supposed transcript of a foreign broadcast from years after the fact, entire dependent on those good old unnamed witnesses, which lodges charges against “a Catholic priest” and “two nuns” but can’t even name them, etc… Before that the article on Vietnam provides no evidence for most of its assertions. It even praises the Ho Chi Minh government as “freedom fighters” (!) who supported religious freedom (!!) when they were really the same as any other Marxist tyrants. Censorship, religious oppression, torture, and "re-education were the norm in North Vietnam just as in Mao’s China and Stalin’s Russia. Also note that there the reference is “MW”, but nothing is listed in the references for “MW”, so there really isn’t a source. And the same is true for many of their other claims.
