Yeah, it's reached a point where an all-white cast strikes me as weird and I'm sure it does others. Now that we've tasted diversity, a lack of it really shows up IMO. In the last few years, I've read 2 series of books in which the cast gradually pair up and live happily ever after. One series surprised me by having everyone be straight. Twelve people and no one is queer?! I even wrote the author to share my surprise and we had a nice exchange.
