The way I see it, you can either pass a law "banning the pixels" or try to change human nature. Which will be easier and which one will address the issue sooner?
As I said below in another thread, banning discrimination on the basis of judicial and criminal history would immediately and obviously "change human nature" because the practice of discrimination on the basis of these histories occurs openly as a best practice under standing precedent in almost every area of society.
It's literally on application forms -- how can you NOT think that requiring "the question" to be absent from the form would change the conversation about this kind of discrimination?
