I'm not going to lie and say that the division isn't high, and that most of that division isn't centered around tolerance/culture wars. But I think it's extremely hyperbolic to suggest that the US is not comparatively one of the most tolerant countries in the world or that it doesn't have a culture of tolerance. Anywhere that you have diversity, you're going to have some intolerance. If you don't believe me, ask your average European about their opinions on gypsies or Muslim refugees.
