Isn't that better? Like if you're selling sailing equipment, I can't imagine that excluding <ethnicity> possibly make things better for those people who also happen to like sailing.
If I sell sunscreen, how do I target people who get sunburns ? (don't take me too seriously)
This assumes a product has no legitimate reason to be racially targeted. There aren't a lot of white people buying afro pick combs.
You can still target for afro though. Which may be better than targeting racially where afro doesn't apply for majority anyway.
