As dumb as it is still, I can understand how people like brendan1903 bring up the issue of why there’s no condemnation for the non-Jews killed in these camps. I can’t say about other countries, but in many schools in the US there is a very strong focus on the Jews interned and murdered, with rather passing mentions of anyone else. I do remember a couple mentions of the pink triangle, one of those actually from a movie shown in class taking place in Germany. In the movie an actresses stylist talked about having a date with another pink triangle. Unfortunately, I don’t recall the movie.
So, with Jewish interment and genocide talked about every time World War II is brought up, and sometimes a passing mention of other targeted groups, I can actually understand why brendan1903 would see no condemnation for the other mass murders. He’s still an idiot, because he never paid attention beyond school. Plenty of books and movies covered it through storytelling, and plenty more non-fiction details it, including at least one source I had found that showed that it wasn’t just yellow stars and pink triangles, but a pretty elaborate code telling all kinds of details just by shape and color of the badge that “undesirables” were supposed to wear.
