Is it racist for MSM to only hype up any white on black crime and never hype or focus on black on white or black on black cimes?

Hell YES, it sure is.

well when white guys commit these mass shootings which is everyday the whole world ignores the fact that it's white on white crime

They clearly have an agenda. How about all of the east Asians being attacked in Oakland by younger black men? notice how the media doesn’t pay much attention to it. How about the black 18-year-old in California who kicked elderly Sikh man with a turban and then spit on him? It was caught on surveillance video. Imagine the outrage if a young white person attacked an elderly black man? Van Jones and Don Lemon would be lecturing us on the dangers of white supremacy. Al Sharpton and the likes would be protesting in the streets demanding for justice. We wouldn’t hear the end of it for a couple of months

how about the jasmine Barnes shooting in Houston Texas when it was revealed that the shooter was actually a black man and not a white man it was no longer newsworthy

How about how the rape murder and torture of Corrina Mehiel in Washington DC in 2017 was not a big story at all?

These are all things to think about

Yes, they don't report on it because doesn't fit their racist, anti-white agenda.
