I do think that GP made a gross overstatement, but I don't think the similarities are irrelevant and/or superficial. These are the same tactics being used (to a lesser extent and in a different context) towards a similar behavioral end. Reflecting on that might be worthwhile. Even if you decide that they are worth using to some extent to bring about whatever ends you desire, you should at least know the devil you're dancing with.

Your reasoning has always been the justification for the horrors of re-education camps.

Nonsense. It's like saying "arguments in favor of industrial production have always been the justification for the horrors of labour camps". Or "arguments in favor of the rule of law have always been the justification for the horrors of police abuse". There's a superficial similarity, but totally different scopes, methods, and outcomes.

In this case, I'm against things like the e.g. Native American re-education camps, because I believe that they have the right to their own culture (plus, they were there first).

But I'm in favor of mere education camps, also known as schools.

And guess what? Populations that was sent to "re-education camps" also are in favor of such things. They also have schools (or similar processes and teachings for their youth).

There's a whole lot of difference between a society teaching its children (which is how we're not animals merely grazing grass but have culture, technology, science, etc), and to be taken from your family for forced re-education to a different culture you don't belong to (and who is even adversarial to your people).
