I was in Amsterdam for five days in May and found your people to be really open, charming, and tolerant. I actually really liked the culture; everyone just goes about their lives doing whatever they damn well please and if someone's being an asshole people tell them to knock it off. American culture, on the other hand, can be VERY judgemental and VERY conformist, so I can see how such openness would cause some of us to become very, very paranoid :)
