I don't always no them for sure!
This is going to sound very judgemental but I don't know another way of putting it: Most Danes don't go into mockery and name-calling instantly. Most are able to have decent conversations with people we disagree with. It's something we value very highly and in school we are encouraged to have our own opinions and make valid arguments for them. It's perfectly fine (in most cases) to present a differing view even in an exam situation, as long as you can present good arguments for your view.
You can go ahead and be judgmental: it is definitely a current failing in the United States. Exercising good judgment should be honored, not castigated; sadly, "being judgmental" is definitely one of the current un-politically-correct abilities in our society.
My near family is mostly English, German and Irish. In this culture, we tend to be less the hot-heads and more the ones who will avoid confrontation. We are having to learn how to politely stand firm because otherwise we end up getting run over by people who like to yell and scream and call names rather than have a reasonable argument.
I'm shocked at how difficult it is to find people to have the kind of arguments I'm used to being able to have, where you can present different views without descending into stereotyping, mocking and ignoring the person you're conversing with.
It is sad. I love a good debate, it's often how I grow and figure out what I really believe and why.
