It's inextricably woven into the very fabric of Leftist thinking.
You know, that is so true. I just had a spirited exchange with a leftist who sent me two MediaMatters links to ‘prove’ that conservatives are racists. And this leftist admitted, when she sent the links, that some quotes were taken out of context. Now what mature person would consider that a valid much less persuasive argument?
Never fear. I pulled out all the stops [in my rebuttal] and gave a lot better than I got. ;)
