Why don't the liberals make fun of them and drive them out of their movement then? Poor southern whites used to be Democrats till the self-proclaimed "heirs of Franklin Delano Roosevelt" decided that FDR was planning to legalize sodomy just before his famous last headache. If liberals don't want the votes of poor whites who are government dependents because of their religious conservatism, why do they give a free pass to Fundamentalist Blacks?
The same reason Republicans will give a pass to immigrants that are on the welfare system but not blacks.
