They are working against their own interests because the effects of abortion are conteracted by the rewarding of “baby mamas” with billions of dollars in all kinds of welfare benefits. The Democrats reward them for having illegitimate kids then give them the option of abortion if they don’t choose to carry to term. The Dems benefit either way because the welfare keeps the Black Democrat voting population increasing but the availability of abortion keeps the Dem voting feminists happy as well. So two Democrat voting constituencies with conflicting interests are kept happy as they both get what they want.
Both blacks and whites are being replaced by Hispanics; the impact is felt worse by blacks as they are shut out of jobs and political office. Cities are increasingly electing Hispanic politicians, and blacks are confined to the worst areas with a “moat” of Hispanics encircling them as a buffer for whites.
Whites themselves are availing themselves of the freebies in much larger numbers than blacks at this point; they learned well, and will force reform by overloading the system. Obama has no more money to dole out to them (unless he keeps devaluing it).
