I don't see how you could even have ads that aren't discriminatory if "proxy characteristics that correlate with age or gender" is enough to be discriminatory? If you put an ad next to a barbershop, then that ad is targeting men through "proxy characteristics that correlate with gender", because it's next to a service that men are much more likely to visit. Is that illegal discrimination too? Are there officials that somehow calculate the locations where you are allowed to put advertising so that it wouldn't discriminate (close enough to shops that both men and women visit)?
