Here is a modest proposal: practice what you preach.

Take multiculturalism. Some of the biggest fans of ethnic and cultural diversity tend to live in some of the least ethnically and culturally diverse enclaves of our major cities. While these multiculturalists bask in the warm glow of self-satisfaction at the high levels of openness, tolerance and enlightenment they exhibit, the massive social experiment they sponsor and cheer on largely unfolds somewhere else.
