The fundamentalists are insistent that they know best. It's a dictatorial attitude towards personal morality, which is a modern creation that came about in the 19th century.
I'm not Mother Teresa. But I'm not Frank Bough, either. I am getting older and a bit more sensible. I'm not going to be popping up in dungeons every six months. If you catch me preaching fidelity while I am shagging chickens then throw the book at me. Otherwise, leave me alone.
I'm not like a politician that goes around talking about family values. And I can't get fired from being a funny person because I did something that most people are disapproving of. I think people are just obsessed with this morality that people perceive as being the right and wrong way of doing stuff.
