Billygoat....I can understand where you're coming from, but here's a story that I think you'll find humorous!
My son is 6ft 1in, he has for the last 15 years worn his very dark hair very short (i.e. he shaves it to a 1/2 inch fuzz), he also sculpts his sideburns and chin hair......wears Doc Martins, blue jeans and an old green fatigue jacket. In December 2001, he and his fiance spent a week in Washington, DC and decided to visit the Holocaust Museum.......yes you guessed it! He was pull aside after entering the building and searched as he looked like a "skin head"...funny as my son knows more about the holocaust than most Jewish people.
Flash forward, April 2002...my son and his fiance take their long awaited 3 week vacation to Europe...Italy, Germany, the Czech Republic....not problems at all with customs or security....they arrive back in Orlando, FL go through customs and security...take the shuttle back to the main building and boom.....he's stopped and taken to a back room to have his luggage and his body searched! Why....because he had dark hair and they we're pulling dark haired men in that day (bear in mind he'd already been through 2 previous security checkpoints).
People are going to stereotype....it's not right by it's a fact of life and as he said......hey Mom, I had nothing to hide!
