Note: That post is a response to the OP, and a rather weak response saying it "may not in itself be discriminatory — just as it can be OK to run employment ads in magazines and on TV shows targeted at younger or older people" But propublica's article is also weak. Its Facebook examples are stuff like "ad targeted to ages 21-60"
