Call me a knee jerk reactionary, but since this idea comes from the liberal left, I have to think it is a bad idea. After all, the liberal left gave us the welfare state, separation of church and state, sex education, abortion, NARAL and the ACLU.
And that's only in the United States. Don't forget the anti-clerical Jacobin Reign of Terror in Revolutionary France and the Marxist Bolshevik Revolution in Russia.
