NBA's Ben McLemore, Kneeling NFL Players Aren't Representing America

Ben McLemore has strong words for kneeling NFL players ... telling TMZ Sports they're not only disrespecting the nation -- but their message is getting lost in the controversy too!!

The Sacramento Kings guard opened up about the issue outside of Avenue in Hollywood ... saying he believes NFL players should follow the NBA's lead -- and stop kneeling during the anthem.

"You should always represent our nation," Ben says. "That's how I feel. I think you always should."

McLemore also says NBA players are fighting social injustice the right way ... and appears set to give a lengthy explanation on why -- but the dude gets yanked into his car by some friends!!
