Then explain why you don't see this behavior from any other ethnic group.
I work at an inner city hospital; one of the top trauma hospitals in the country. Trust me, there are whites, Hispanics, Asians, etc that behave this way. They just don't get the same press. The common denominator between them all is that they live in the welfare/entitlement culture created by liberals, with complicit GOP support .
What's interesting is that you do see this behavior from white people--in the UK, where liberalism has worked the same cultural damage on the white underclass. It's not behavior limited to blacks, but is seen in any group raised and nurtured with liberal principles.
