Progressive Intolerance

I heard an interesting story recently. Studies suggest that progressives are 17% more likely than conservatives to say that they not only hate the views of people on the other side of the political spectrum, but that they hate the people themselves. This does not necessarily mean that conservatives are more moral than progressives (they aren't), but it doesn't speak well of the progressive value of "diversity" if those who propagate it are unwilling to tolerate people who hold views different from their own.
