There's a troll who constantly posts vanities on FR, all with a different take on the same basic theme. Sometimes he pretends to be a liberal wanting "honest and rational" discussion. Sometimes he's a kid asking all sorts of questions about conservatism. Sometimes he just asks random questions. As soon as I saw this thread, I suspected it was him. No real way for me to know, though. I don't have the all-seeing crystal ball that the mods have.
Part of the problem is that I, and a lot of folks here, would welcome a few honest liberals. Trolls have learned to try and exploit that. But they can only keep up the charade so long. They are so used to relying upon regurgitated spin that they can only pretend to be something else for so long before they run out of neurons to fire.
