I find the insight that my peers have shared in those events / classes extremely eye-opening. Yes, race has been a hot issue in the United States for a long period of time. We need to continue those thoughtful dialogues in order to respect and empathise with individuals' unique experiences.
I like the US as country and I love Americans as people. I feel comfortable enough generalizing to that effect. But I'm often so overwhelmed by "American-ness" these days, that I feel in danger of neglecting opportunities for new perspectives and daily variety in favour of the US. It's a real effort to escape from this risk in the Britain of today, and indeed in much of the Western world. One country should not hold that particular power over the rest of the globe.
