I will read the article and incorporate it into my view of things. I don't get the impression that you are prepared to evaluate information in a similarly open-minded way. You remain silent on all the points I have raised. This makes it clear to me that you are an ideologue.
I already knew about US immigration services abuse. It's absolutely a problem. It seems like a non sequitur in the discussion though. The actions of ICE in the US since Trump was elected don't seem like they have any relevance to the educational problems in Latin America in the 60s though? I mean, unless ICE now has time machines. If that's the case, I will absolutely start worrying. A lot.
