I'm Dutch too! My parents have been a host family for a international dance festival, where dance groups from several countries come to perform for a whole week. One of the groups once told us they were surprised that our land was so much cleaner than other countries! That was the thing they immediately thought as soon as they landed on the airport. Oh.. and they thought the mailboxes were not for mail, but for garbage. :p
I lived in Holland until I was 12 and now live in Spain. I was from a small posh village and most people there were not very nice, quite cold and closed minded and I was constantly bullied over absolutely nothing.
However I have to say most people from Amsterdam are a lot nicer and friendler but in general I have had quite negative experiences with other Dutch people and frankly have no Dutch friends only Spanish friends. I also prefer Spanish girls over Dutch ones.
Most racist people I have ever met with the most paranoid airport staff. I can't walk for 5 months through schipol without being pulled aside. Talk about paranoid
