Corollary: any society which does not tolerate diversity on any topic of consequence is by that fact alone no longer pluralistic, and if this lack of diversity is enacted by violence–whether directly physical, or by eliminating the ability of dissenters to express their views–that society is tyrannical and inherently, definitionally anti-Liberal.
With regard to the Phil Robertson case, what is at issue is neither whether or not homosexuality is moral, nor whether it is moral to believe it is immoral. What is at issue is whether we remain a pluralistic society capable of resolving or at least reconciling our difference through open dialogue, or whether we are becoming mon-archic–an order based on One, on one vision, one view, one way of behaving.
As a practical matter, we have in this country competing societies, competing social orders. One remains pluralistic, and the other is patently Fascist in habit and expression.
