Not really the point I'm making nor the equivalency I speak of - intolerance possibly breeds extremism is my point regardless of the source material. The equivalency I was referring to was someone referencing something they clearly were not offended by trying to equate that particular image to something someone else expressed finding offensive.
I say it is irrationality that gives way to extremism. I say it is rational thought that squashes extremism, and we should be peacefully intolerant of irrationality.
