I didn't know about that. But it still doesn't warrant banning religious schools completely due to isolated incidents, and that was sort of the point I was making earlier. This is what the author was hinting at needs to be done, it's not an uncommon sentiment among the right either.

There are a few bad apples among every religious and non-religious group, it's just how it is. Doesn't mean one should attack an entire group, unless one is in a crusade or something. For every ISIS supporter I bet you one can find 10 pro-violence far-rightwingers. That doesn't mean one should lump the entirety of that side of the political spectrum and call them a danger to humanity/minorities. It's not fair to do so with the right, and it's not fair to do so with the muslims.
