Iv had my ears gauged for over 10 years. I dont beleive its cultural apropriation. White people use to be considered barbarians back in the day. Celtic and germanic tribes would modify their looks and do tattoos, whose to say given enough time they wouldnt have started gauging their ears. Plus why worry about cultural apropriation when all christians, muslims, jews and any other follower of any organized religion is apropriating anothers culture. Do what you want for you, and fuck the haters.
