I actually don't know Berber Libya is. Like Algeria, most Libyans are ethnically mixed with Berber. However, they seem to be largely Arab in their culture. Berbers, who still identify as Berbers in Libya, are like 10 per cent of the population.
Libya's Berbers fear ethnic conflict
It is kind of intellectually lazy to keep referring to anybody that practices Islam as being Arabs. I keep going back to the basic premise that only people from Arabia are truly Arabs. A dude from Mali, Pakistan or Indonesia that practices Islam is not truly an Arab, but I think that people keep interchanging those things.
