Seems to me that humans have borrowed from other cultures probably since the Homo Sapiens, Neanderthals, Denisovans and whatever other hominids were around then discovered each other and started sharing living spaces. I understand the part about taking something meaningful, historic or sacred to a culture and using it in a mocking or frivolous way (Indian Headdresses for Halloween, native american team mascots, etc). But adopting other cultures food, style of dress or hair and incorporating it into your own seems to be very different. I see no disrespect or harm in something like that. The dreds, to me, fall into that category.
