A lot of Baloch who are pro Baloch nationalism are quite articulate, educated and "relatively" well off.
BLA's Majeed Brigade is full of neat & clean, tech savvy young men (and women now?). Atleast from what I've noticed.
One particular trait of Baloch nationalism has been the extensive involvement of women. It's very hard to find any Baloch protest without women participating in them. (peaceful protests)
But women shouldering with radical Baloch is something new. In hindsight, one can claim it was a very natural progression.
Why do they do it? What are the causes? et al are some questions to which you will not get your answers here.
