I consider myself as leftist as possible with a functioning and informed brain. Yet I know that "left leaning" and "right leaning" are mostly biases that we use to orient ourselves in a world too complex to be fully understood. EDIT : I think that everybody should read http://righteousmind.com/ http://righteousmind.com/ from J. Haidt. Wrt to whether differences are biologically based or not, I'm convinced that one day, we'll look back at the Nature vs Nuture debate like we do with the Particule vs Wave debate for light. The sooner the better. As to which part was so offensive, it's akin to wonder which spells got the witch burning at the stake. Witnessing so many smart and compassionate people join the angry mob really scared me : I have no reason to believe that I would not do the same if the right buttons were pushed.
