Gangsta rap is a genre of hip hop that reflects the violent lifestyles of some inner-city youths.
The subject matter inherent in gangsta rap has caused a great deal of controversy. Criticism has come from both left wing and right wing commentators, and religious leaders, who have accused the genre of promoting homophobia, violence, racism, profanity, promiscuity, misogyny, rape, street gangs, drive-by shootings, vandalism, thievery, drug dealing, alcohol abuse, substance abuse and materialism.
Hmmm... sounds lovely, doesn't it?
It was also noted that gangsta came from the word gangster which is described in this way:
A gangster or mobster is a criminal who is a member of a crime organization, such as a gang.
I am thinking this is not something with which we should be associating. Just call me conservative. :)
