It does get tiresome hearing this same old tune all the time but like your post points out these clowns are going to stick with this twisted idea of theirs until the day they die. I figure the best thing we can do as citizens is simply to stop watching them. Since I can't stomach listening to them for even a few minutes I've done myself that favor years ago.
Conservatives have been so thoroughly intimidated over the last two generations by the mere hint of a charge of racism, that they have abandoned the political field to Democrats on many, many issues and in many, many geographical locations. That is why I have so often said that Tip O'Neill's maxim that all politics is local should be amended to say, all politics is racial.
As the country becomes more and more Hispanic, expect the emphasis to shift and expect the process in many ways to start all over again. It worked very well for Democrats when they applied it to women's rights and it might yet work for them on homosexual rights. In other words, there is no end to the ethnic, racial, and gender good liberals are prepared to do. Yet no issue provides liberals with the massive throw weight that alleged African American racism provides.
We conservatives must find a way to make the case that every time a liberal sets out to do good he is stealing a little bit of somebody's liberty.
