I could be mistaken but I believe those charts may have been camp specific. They’re often identified by camp, and there were a lot of other categories which weren’t on there. POWs got an uninverted red triangle, so those traffic signs are bad. Roma males brown. And there were more sub-classifications than that chart shows. Which is what makes me think they’re camp specific.
Well, I’m not surprised that the Germans would organize their evil with emblems and insignia.
Can not see what it has to do with the President, though.
