IDGAF if they fly a Nazi flag, it's their deal, not my circus/not my monkeys rule applies. I'm not going to be dying to meet them, or want anything to do with them, but it's their choice. A shit-ton of people in this part of the country do fly Confederate battle flags, I also don't care about that. Or Union Jacks, despite most of my ancestors being victimized by the English. Ditto for Imperial German flags. Ditto for United Planets, UN, Sunshine, Rainbow, Enviro-wienie, or whatever.
Because unlike all the screamers, I am capable of minding my own business.
