I remember reading something like this a few years back in The Guardian. 

One article was about 'refugees' being housed somewhere in some poor part of NE England and they (or some leftists) complained that the houses they were in had red doors and this was supposedly a way of marking the houses out as being occupied by them, and it was likened to Jews in Nazi Germany having a yellow star of David painted on their doors. 

Another was some asylum centre in south Wales where the people staying there had to have a wristband or something like that so they could eat (apparently it was so it could be scanned before they collected their meals, so everyone got their 3 meals a day and to stop people eating more than their fair share and depriving someone else of their meal). But the article portrayed this as being like Jews being tattooed in the concentration camps.

Any good thing we do just gets thrown back in our face. Fuck these niggers and fuck the left.
