BSL for us.
But I must admit, my idea of long for other races is not BSL, midback length for "others". I've never actually thought of it until this thread, I guess it's based on what I am used to seeing. But I have a white coworker whose hair is about BSL and I don't think of her hair as being LONG whereas when I see a black chick with BSL length hair I think of her as having long hair. Just my perception.
I also think you have to take your statement turn it around and see if you agree.
If you think BSL or longer is long that means you consider anything shorter than BSL as short hair. That makes no sense to me, IMO.
