You cannot argue logically with these liberal haters. Politics and destruction of the right are their religion. No amount of argument will be persuasive, just as those of us who have a real religion can't be swayed by mere argument. Actually, liberalism may not be their religion, since religions generally have some sort of purpose and add meaning to life. Certainly however, logic and rationality do not play a part in these people's lives. It would be funny were it not so sad.
Unfortunately, there are legitimate liberal positions to be taken on most subjects (I disagree with them, but they are legitimate). We all lose when we are not called upon to rationally defend our positions.
Liberalism/socialism is really cultural Marxism - an ideology. There was a very instructive essay about this posted (somewhere) yesterday. They use Political Correctness to gain and keep power. Any argument or position stated contrary to their "beliefs" becomes "unspeakable" because it is "hurtful" to some group or other. They cannot win in the world of discussion, so they use word/thought control to dominate.
I would bet that this WP author is very young and has been very insulated from exposure to any conservative conversation or opinion. How he, as a person who makes a living by writing, can brag about being ignorant of blogs, is illustrative of the liberal mindset. They do not search for knowledge, because they might be exposed to something that "offends" their sense of what is "truth".
