Honestly, I'd never give this sort of thing a second thought, but it being presented here makes it pretty open to response. I think I'd have been okay having never read about it, though knowing how often this sort of thing is brought up here (which honestly, I find a little strange) I guess it was inevitable that I would actually pay attention to it at some point. In fact, my original response to the subject of these crazy ladies was a very sarcastic "Thanks for sharing." Honestly, I'm mad at myself for spending time reading those ridiculous arguments, where I never would've found them otherwise. I mean, I get that it harps on the point of this topic, but it's from that corner of the internet that most people ignore in the first place.
Also, they aren't very vocal outside of their little blogs from what I understand, so as long as they stay under their rocks, they don't have much of an adverse affect on people. I mean, PL has a point; I'm pretty sure you have to look specifically for this crap in order to find it; I certainly never would've wandered into it on accident.
