Rap Legend Twista -- Little League Is Racist ... For Stripping Title From All-Black Team

Chicago hip-hop legend Twista tells TMZ Sports the decision to strip Jackie Robinson West of their U.S. LLWS title wasn't about following rules and ALL about one thing ... racism.

Team J.R.W. became the darlings of the 2014 Little League World Series, becoming the first all-black squad to take the U.S. crown ... earning them instant celebrity status and even a visit with President Obama.

When it was announced earlier Wednesday that the tykes had been stripped of their title due to a falsified boundary map, some people called B.S. ... including Twista.

We spoke to Twista -- one of the most celebrated rappers from the Windy City -- and he tells us that he thinks the whole thing was totally about discrediting an all-black team.

"I'm outraged. You don't see this extensive of an investigation happen unless it happens to black people."

Twista also says that there's a legit reason why some of the boys traveled out of district and that the higher-ups at Little League headquarters just don't care.

"There was a park in the Dolton area that got torn down, that made the kids have to even play at Jackie Robinson. No one pays attention to what they have to go through to play baseball."

He didn't stop there ... Twista essentially says America is still uncomfortable with a group of black kids succeeding in the country's celebrated pastime.
