Oh I'm well aware (almost) no one will come out explicitly and endorse concentration camps. What they do is almost more insidious, they justify them. They rationalize them. They spin them as something they are not.
I'd rather someone be an open Nazi than to perform their mental gymnastics in public to avoid challenging their world view on something as simple as "mass interment camps are bad." "Well you see they aren't interment camps...they were criminals anyways...how dare you compare a work camp to a death camp?"
It's sickening, all of it. Your spin of "it's not the same as the holocaust" (no one said it is) and "yeah but whatabout the US!" is sadly par for the course.
