You will undoubtedly be castigated and shunned for telling the truth, that it's often the locals who start these things. Years ago, I recall watching a young Marine who had been pressed to the Popeye point ("Dat's all I can stanz, I can't stanz n'more!") take on three locals and send all three to the hospital. Absolutely nothing happened to them beyond their broken bones and missing teeth. The Marine was reduced from Lance Corporal to PFC, fined a months pay, and placed on restriction (house arrest) for a month. I'm 100% in favor of nailing a Marine to the wall when he's out of line, but to paint with a broad brush, as you stated, doesn't work and causes hostility. Quite honestly, I though we had advanced past the point of blaming and discriminating against ALL of any group for the actions of a few.
