IIRC members of undesirable groups were required to wear an emblem based on their undesirable characteristic. Jews wore a yellow "Mogen David" (star of David) and homosexuals wore a pink triangle. I assume there was a punishment for not wearing the emblem and that the emblem could get you barred from certain things. It was a long time ago and I had nothing to do with it, I was only following orders.
Never knew about a pink triangle. Now replaced with a rainbow flag
