I confess, I've never heard of any such organizations nor, in the first world, any significant or systematic violence directed against Muslims.
In India, yes, the Hindu nationalists will take on Muslims for being Muslim, and have done so on an ongoing basis. Here in the West, though, it's pretty much live and let live... or am I mistaken?
The guy is associated with an organization which put out videos accurately depicting jihadism. Any defense against jihad is "violence against Muslims".
