I think the broader thing to consider is that any home with any political ANYTHING displayed. Is one that must virtue signal its allegiance to the system of authority publicly,purposely & proudly. In order to give confirmation bias to others whom otherwise wouldn't care, that they too must have an opinion on things they otherwise wouldn't, due to the simple fact that some agency will force upon them some majority decree upon them.
These that display these things will gleefully decree that the heinous acts brought onto its fellow man were "necessary " for the greater good and an achievement for society to relish in.
Its a mental illness at this point.
