That's not true and you know it. Specific threads, posters?
I'm not going to name-call. I will just point out that threads about moral issues and/or social conservatism of any kind draw a group of posters who preach the "I'm the master of my fate, the captain of my soul" line. They use this to justify the sort of absolute personal autonomy (and consequent freedom from both social convention and moral obligation) that our leftist friends are celebrating so vocally these days. If I called these people "libertarian," I would be raising their drunken rantings to the status of a philosophy.
Actually it is true.
Enjoy, if you have a few hours to read through it:
