I listen to them for the same reason Right Wing Watch listens to them: for the insanity and facepalms, and to hear what arguments they use so I know how to counter them. I admit, it does get stressful at times, what with all the anti-gay bigotry and anti-Muslim paranoia. But at the end of the day, they're only hurting themselves, as their irrational hatred and ignorance eat away at their humanity.
