Personal responsibility is great and all, and the white landowners who enslaved most of the ancestors of these people didn't seem to know a damn thing about it.
Slavery, that was abolished 166 years ago by force of arms with 600,000 mostly white deaths, cannot be blamed for the way people behave today, especially given the access to free public education, free childhood immunizations, laws preventing discrimination in hiring, etc.
The welfare state is more a cause of minority crime rates than slavery. Your argument might play well on the Democrap Undergroomed Web site, but not here at FR with educated, informed, realistic Americans.
