Buddhism certainly still used it, althoug the Nazi's did spin in a few degrees.
If the confederate flag has to go, the USA flag has to go.
It was under the stars and stripes that the US government sent blacks to Vietnam to die after a fabricated incident, it was the US government who gave blacks syphillis under the tuskegee incident incident, it was under the US flag blacks are currently being robbed of their gun rights, have their hard earned labor stolen away from them, are used for political gain, etc......
Anyways I for certain dont ban any flag including the Nazi's. Ill tell you, if I saw a restaurant that was flying the Nazi flag I dont think Id be visiting there, but its their right to have that. Once you take others rights away to be politically correct we all lose our rights.
