I still remember a couple of the leaders (who are Mormons) of that extreme group (one I think British and one American) recounting what allegedly led to them wanting to ban porn.

They were abroad in some country in Europe, doing work for the Church, when they saw someone reading a magazine with someone being sexy on it.

They were outraged that such a magazine could be allowed to exist and they vowed from that day forth that they would rid the world of it.

It's all crazy.
