Of course there are deeper motives behind it, but that doesn't mean I have to like it. Besides this doesn't mean I can't like Dutch people. It's also not the fact that the Dutch nation would be proud if Holland were to win the WC, it's that annoying "party attitude" some Dutch have. Somehow painting the town orange is annoying to me while the Spanish, Italian and Brazilian can have whatever festa they want

.
This attitude is even strengthened by your players if I might add, Kluivert, Seedorf, Davids (I actually do like him) and Van Nistelrooij haven't aided your case.
I wouldn't know if that part about active hatred is actually true. To me the 29th of June was sweet because it was an historical Italian victory, and yes, also because the Dutch were so confident to win. I would probably have had just as much fun had it been England or Germany though.
