> The US also rounded up racial undesirables into camps and used them for labor

This was also bad, yes.

> there's a reason that Roosevelt is looked upon more fondly than goddamn Hitler

Sure, but "less bad" isn't the same as "internment good", and the winners write the history. I am a fan of FDR! But he did some miserable shit to win a war that needed to be won, some of which we cringe at now.

A handful of Nazi war crime prosecutions fell apart because Allied troops widely did the same thing, for example.

This doesn't respond to my point at all. I tell you that it is ahistorical, dishonest, and disrespecful to equate subsistence farmers being forced into subsistence factory work by globalization and economic conditions with the holocaust, the mass deliberate extermination of Jews, Romani, Slavs, the disabled, etc. because one uses slavery and the other uses something that you consider comparable to slavery. Your answer is that less bad things are also bad? Sure, yeah, but they're nevertheless less bad and shouldn't be treated as equal.

Not to make light of poor working conditions, dirt wages, and child labor. They can be and should be addressed. But they're not genocide and throwing out a "Arbeit macht frei!" is gross here.
