A LOT of difference from being a victim or being left alone is purely primitive. How you carry yourself and how you act, be it predator or prey will more likely get you out of trouble unless its unavoidable. Now days the "tacticool" look is so popular that it would not be uncommon for the average joe to misinterpret someones wear if it was toned down enough. i.e. Wearing real-tree could just mean you're a hunter, or wearing solid colors could make you look like a skater.
I agree that waking people up is very important, and needs to be done. But it is best to "test the waters" of someones views, possibly planting seeds of ideas that maybe the way the MSM portrays things isn't true. If you bombard someone who is fully asleep with the truth they will usually either react by:
1. Shutting down and not talking to you for a while at least
2. Becoming argumentative or even combative
3. Break down emotionally
the "Grey Man" method has a time and place, knowing when to use it and how much will come with time and experience. Hell, try it out even now. Dress 0 and walk around the mall gauging peoples reactions. *Then dress a little more overt and see what happens!
* Don't necessarily do this, you will probably get some unwanted attention! lol
BTW I love the new style of Alta Superflex Knee pads, they rock lol
