In my youth, somewhere in the late 1990s, when I was a goth or a punk or something, I had a t-shirt proclaiming, “Ignorance should not reproduce”. Along with the text there was a provocative image, which included the Christian cross.
Back then, if you were an educated liberal type, who valued reasoning and evidence, the scientific method, free expression and broadly progressive social values – the kinds of values championed by civil rights movements – there was a decent chance that you felt yourself to be battling against a stuffy, illiberal Christian orthodoxy that, to a considerable extent, held the reins of power, especially in the United States.
