Personally I've never been bothered by that kind of marketing.
I take it more as people with x racial background are likely to have similar hair. This product is targeted towards y hair. There is a logic to that that doesn't seem odd to me in the least. Unless a company came out and explicity stated that a product was ONLY for a certain group and no one else could use it or that group couldn't use any of their other products would I be bothered by it.
I might just email them to find out the ingredients. I am curious now.
