> Ditto for "black girls": either your looking for porn or for stock photos. What other intentions do you have with such a query? Consider the possibility that the user is a black girl, or her parent. Generally, I'm careful not to assume I can anticipate the perspectives of everyone else.
Do white boys ever enter the query "white boys" into a search engine? I assume some HN users could speak to this...
The phrase "white boys" in general seems to be mostly desexualized. You can call someone a "white boy", either as a mild insult (like describing something as "vanilla") or a term of endearment. I think that's predicated from most people (in the U.S.) realizing that white boys/men are the status quo.
I'll ignore race and just say that I think the word "girls" in general has far more of a sexual/gendered connotation in U.S. usage. "Boy/Man" is considerably more generic and all-purpose. I use "Boy/Man/Guy" in casual conversation regardless of audience gender, e.g. e.g. "Boy, that was fucked up!" or "Man oh man that's got to hurt". I can't think of a single time in normal conversation where I would ever say "Girl" or "Lady" without referring to a female.
