It's not that the L.A. Blacks are soft, it's that we're vastly outnumbered. L.A. and California in general isn't a black friendly state like the South or the east coast is.
Hispanics know this which is why they show blatant racism towards blacks in California. They're doing classic racial intimidation tactics like fire bombing black homes, spray painting racial slurs on black homes to force blacks out of certain neighborhoods. That's the shyt white people were doing to blacks in the South back in the day.
