Even Japan is getting a case (so I hear).
In all seriousness, from a spiritual standpoint, I think the Dims have told blacks, especially black women, over and over and over an over that the deck is stacked against them and that they have to go out of their way to be respected. A spirit of fear or inferiority can bring about a behavior of fragile superiority. That's where you put up a seemingly rigid shell of strength (I am black woman hear me roar) so people don't see how weak you think you are underneath.
The black women I know from church who live worldly lives (and sometimes come to church dressed like they're out clubbing on Friday night) act a lot like that. But the ones who've truly gotten to know Jesus and see themselves how He sees them (and change their lives), don't act like that. They don't seem to operate on a hair trigger of being disrespected because they know that Jesus loves them enough to shed His blood for them.
