You are so wrong about the red light district. I am Dutch and live in Amsterdam almost my entire life. The red light district is not shady at all. Plenty of hipster bars within and around the zone. Hardly any dealers walking around anymore these days. Red-light district is both popular by locals and tourists. It's the safest city center neighborhood. The place never really was a shady place. Not even in the 17th century. It's a place of obscure trade. Sometimes a bit too much for outsiders. The available sex and drugs in the red light zone is not linked to criminal activity. It is heavily regulated with many different institutions watching over it. No Dutch girls working behind the glass? Again you are so wrong. Yes the mayority are Romanian and Bulgarian. But the private clubs are mostly Dutch girls.
