Bullies to left of them
Bullies to right of them . . . 
The right have to disavow their thugs when something like this happens.
The left have to disavow their thugs when violence occurs in "peaceful" demonstrations.
Muslims have to disavow their thugs when preachers preach hate.
If we all keep quiet just because they are "our" thugs we will end up being ruled by them.

(My life is much more peaceful now that G&M has limited me to 6 articles per month. I hadn't realized how much time I was wasting in this forum.)
