I'd like to add to what you said: Under the right conditions, and with the right leadership, social ideas can change quickly. Under the right conditions, enlightenment can come much quicker than one would necessarily believe.
I can't immediately define the conditions, but it usually takes a well-organized, self-multiplying movement, or a dynamic leader, or a splash of some kind.
And if you get those 3 things together, you can get somewhere quickly.
This is an important concept. I think that Free Republic is now providing an example of the "right conditions" and some "right leadership" appears to be growing. There are several posters who have begun an active campaign and I hope their popularity grows.
I suspect there are a great black people uncomfortable with the liberal message who might learn to be comfortable here.
