Huh? This is so untrue it makes my head spin. where did you hang out, the mall at Tysons Corner? The people I hung out with were from all over the country and the world and had huge diversity of backgrounds and view points. Contrast to here where apparently you get issued your green suburu with a dog and a "free tibet" sticker when you get your 206 phone number.
Since when does diversity equal Clean, White, Professional and Suburban?
Though I'm sure the people you met there had some enthralling opinions on the current political issues of the day.
