i dont think it was a racist remark, he was probably pointing out the fact that these people sport the dreadlock without knowing what it stands for, it like if i were to dress like buddhist monk and then go out and eat meat. Or if i started wearing a Cross and then worshippeed Buddha or something.
p.s. Australia is a great place to live, hardly no racisism!!! here in sydney, we have Viets, Aborigine's, Irish, English, American, African, Kenyan, Chinese, Koreans, japanese, indians, sri lankens, Tongans, etc.... so many to name
