The following extremely informative video includes an interview (in Hebrew) with the leader of the thugs in Bet Shemesh, as well as some important footage of events (please note that the video includes random advertisements, some of which, according to reader reports, include immodest scenes):
It shows how far apart their worldview is from normal society. I can't think of any short-term solution for this problem. In the long run, however, I think that their society is doomed, due to the freedom of speech and infiltration of ideas that the internet brings. I think that they know it, too, which is why they are getting so worked up lately.
It's good to see a sharp condemnation of their actions, in this report of a lecture by Rav Edelstein of Ponovezh.
