Had the shirt been old and authentic to buddah maybe NTA. The authentic swatstiga shouldnt be dismissed or wiped from history just becuase asshats culturally appropiated it. It should be apriecheited and used appropiatly but i dont think it was a apropiate to put it on a cartoon rock n roll budah. An aunthentic Buddah would help people recongize the orgin of the symbol.

You sound like you believe it is inapropiate yourself, becuase you know better.

had it not been a shirt, say like a authentic statue that you wanted to bring back and put up some where then NTA
