I agree. That is a European trait, and is especially present in Northern Europeans.

They are slow to anger. The Finns are the slowest. So much so they appear very accommodating.

But everyone has a threshold. And our cultural enemies are poor students of history. When Northern Europeans do snap things change rapidly. This is the flip side of reasonableness. When you have been very gracious, and then abused, you are not forgiving. This is what I fear is coming in Europe and North America.
