Metta World Peace BLASTS Boxing Legend -- You're 'Bringing Down' Black People!

Ex-boxing champ Larry Holmes is "BRINGING DOWN" the black community ... all because he went after Floyd Mayweather in public ... so says NBA star Metta World Peace.

Metta's beef stems from Holmes' recent public criticism of Floyd ... when he told Sky Sports Ringside that Mayweather is "crazy" and will irresponsibly blow through his entire multi-million fortune, just like he did.

After reading Larry's quotes, Metta blasted the guy on Twitter ... saying, "Larry Holmes should never call out another product of slave in public."

Peace explained that Larry should be supportive of Floyd because "our community was not fortunate to have finance savvy parents."

"With that said, instead of guys like Larry Holmes bringing down , he should uplift the ghettos."

Metta continued, "People like Larry should be retrieving lost and burnt Black history in Black History books rather than bringing down Black Legends."
