Rarely have I seen the heart of the issue identified so clearly and concisely.
The last thing that Jackson, et al. want is for the progress and realized potential of blacks in America to see the light of day. Many liberals are "good of heart" but thick-of-skull; they are incapable of thinking through the fluff and seeing the essence of the trap that is the welfare state. That is not true of Jackson, Sharpton, and others who know all too well exactly the evil they practice - and smirk while redoubling their effort at lining their pockets.
Well, basically I am of the opinion that the democratic party (since liberals vote almost exclusively democrat) is made up of a whole lot of of ignorant people and a handful of very smart but evil ones who depend on the ignorant ones to justify their continued existence. Anything that promises to bring the typical democrat voter out of that ignorance is perceived as a threat. If they lose the issues that appeal to the gut reaction of the ignorant they have nothing.
I'm sure there are exceptions to my description, but I believe the ones I described are what makes the RATS so dangerous.
