"Excessive Democratic civility" - Yeah, that's not the reality, after you start reading the updates from https://instapundit.com - Democrats are far more uncivil than Republicans. Especially in the non-governmental arena. Higher education used to be dominated by conservatives decades ago. How did that change? Because conservatives still value diversity of opinion, but Democratic leftists don't tolerate dissent; conservative academics hired progressives out of civility, but progressives won't hire conservatives in higher education because progressives aren't civil.
