Isn't Holland a fairly homogeneous culture, the influence of other EU countries notwithstanding?

The United States, with nearly 320 million residents, contains myriad cultures which makes for conflicts that have to be resolved as best as possible. The casual observer of American society is often fooled into thinking Americans only divide things according to race. That's too simplistic.

For example, it's not unusual for national identity to conflict with someone else's way of life. It took years for gays to win the right to march in the New York City St. Patrick's Day and Columbus Day parades (sponsored by Irish-Americans and Italian-Americans respectively).

Years ago the U.S. Supreme Court ruled that neo-Nazis have the right to march in a predominately Jewish neighborhood. There are many more examples -- just this year a local clerk refused to follow a federal judge's order to issue marriage licenses to gay couples because she felt it was against her god's laws

So you can see the problems of a massively multicultural society make it very hard to develop laws and rules that please everyone. I would like to say we're doing the best we can, but I don't think that's true.

I visited your lovely country a few years ago and had a very nice time.

EDIT: Punctuation matters.
