First of all, good job. When you’re right, you just need to hammer the point home and not get diverted.
Secondly, I shouldn’t have said, “Today’s conservative”. I should have said “Modern conservative”, then set up a contrast with traditional conservatives.
More seriously (a lot more seriously) I agree with your two points. But I’ll furthermore state that wing-nuttery is pushed by Bill O’Reilly, Fox News, Limbaugh and the Wall Street Journal’s editorial page. That’s a big problem, as those are mainstream outlets. Serious conservatives have been pushed to the fringe and many unsurprisingly are becoming implicit or explicit supporters of the Democratic Party. As an example see Bruce Bartlett. And those who willingly consume information sources that are demonstrably afactual have issues. There’s a bright line between the WSJ and the NYT’s editorial page: the former espouses crackpot theories whether they involve supply side economics, the tobacco lobby or anthropogenic climactic change.
