I think that there is also an element of a curtain being drawn back, and people finding out that some fellow ENWorlders hold views that some or many might find repellant or even disturbing. I know I have found some I wouldn't want to be alone with in a small room.
If I were most people, I'd probably have put those people on my ignore list. But I have made a point of not using that list for anyone. I learned a long time ago, from a variety of patient and wise people that sometimes the people we don't want to hear are the people we most sorely need to listen to, if we are going to help them...or keep others from becoming like them.
