Uncommon Descent still has some interesting topics, but the authors of the OPs simply do not tolerate any comments that do not validate their opinions.
Worse than this, they label any commenter who disagrees with any of their opinions as a Darwinist/atheist/subjectivist/materialist/communist/progressive. The two most flagrant abusers are Barry Arrington, the moderator, and Gordon Mullings, who posts as KairosFocus.
Kairosfocus’ most recent rants have been about objective moral truths and his charity of the day, self-evident first duties. It has been pointed out to him on numerous occasions that his objective moral truths are nothing more than human behaviours that most people have subjectively determined to be in their best interest if they want to continue to thrive in a social setting.
Rather than address the arguments raised against his views, he repeatedly erects strawman versions of his opponents’ views, and then argues from consequence.
The issue worth discussing here, is whether KF has a valid point.
