Who cares if it was more common at the time? Morality isn't a property of time, it's relative to people. That's why
Bob Blaylock said at no point in time was anyone who practiced censorship a good guy. It doesn't matter at the time if censorship was practiced, the person practicing it was bad relative to Bob's subjective feelings. To my sentiment slavery, murder, rape, those things were always bad, even if they were more common or even legal according to the government at that time. Why would that make a difference?
