In that context, it's hard to see ads blocked by law,even though there's a high likelihood they are harmful to people, and especially to teens and kids.
Other people find Muslims, Jews, Mormons, non-caucasians, breast-feeding mothers, alcohol-imbibers, blondes, Ugg boots, motorcycles, gold watches, crying children, airplanes passing overhead, and dogs to be offensive to their ability to live. Can't ban everything you don't like.
Also, there are already restrictions on advertisements (when was the last time you saw an cigarette ad on television?), and some places are much more restrictive than others.
I simply suggested that, when we're considering hacking our eyes as depicted in the OP to avoid ads, we might consider limiting the ads instead. And that has nothing to do with racism.
