So just because campers fly flags, doesn't mean that they harass others or whatever. Any flag = douche, IMO, unless it's the American flag flying, I don't have a problem flying that flag at campsites.
If you're a part of these AA groups and the Trump flag offends you, I am not sure what to do about that. I am sure flags will be outlawed at camp sites or whatever. The flag isn't racist, the people might be and if they commit crimes then they should be held accountable.
Also, not ALL Trump supporters are racist, but I know they are made out to be.
