Wow.
Can't blame that on gangster rap, hip-hop music, political correctness, Fat Albert, $hakedown Je$$e, the '60s, or any of the usual cultural scapegoats. That's just a nasty, evil, violent, bigoted individual who was brought up wrong and trained to do worse.
Back then it was not acceptable, but was understandable to some extent given the crap many of them had to put up with. Nowadays though, most of the crap is self-administered.
