When I was in Amsterdam for my friend's bachelor party, we walked around the Red Light District. The women stand in a confined room with a glass door for people to look into. Groups of people just walk around gawking at the women (of course, some go in). It reminded me of a Zoo and I felt it was a kind of degrading to women (yes, I was guilty to being a gawker, but I was a non-participant as was the bachelor). It must be my American upbringing that let to my shock as the Europeans had no problems with it.
