He doesn't talk much, but when he does, it's powerful ... so when Marshawn Lynch took the stage at a rap show in Oakland last year, he had a strong message for the crowd -- STOP KILLING EACH OTHER.
TMZ Sports obtained footage of an emotional Lynch addressing the crowd at The New Parish in his hometown of Oakland, CA in the summer of 2014.
Beast Mode tells the crowd he's extremely proud to "represent where I'm from on the national mother f**king stage" ... but says, "I've been losing too many of ya'll."
Marshawn is obviously referring to the fact that Oakland is consistently ranked among the most dangerous cities in the country ... and had the 2nd highest rate of violent crime in 2014.
"We need to be here for each other," Lynch said ... who also explained why it's IMPERATIVE that the young people hear his message.
Check out the clip -- it's a side of Lynch most people don't get to see ... but should.
