NBA's Tobias Harris Rips Govt. Official for Labeling BLM As 'Radical Hate Group'

76ers star Tobias Harris is calling for an elected official in Pennsylvania to resign for labeling Black Lives Matter as a "radical left-wing hate group."

The man behind the comment is Joe Gale -- a County Commissioner for Montgomery County, the 3rd largest county in PA.

The Board of Commissioners is a powerful group -- comprised of only 3 members and they control the legislative and executive functions for the entire county.

Fast forward to Monday ... when Gale issued a strong written statement slamming the protests in Philadelphia as an act of "urban domestic terror."

Gale says the people responsible are "radical left-wing hate groups like Black Lives Matter."

He continued, "This organization, in particular, screams racism not to expose bigotry and injustice, but to justify the lawless destruction of our cities and surrounding communities."

"Their objective is to unleash chaos and mayhem without consequence by falsely claiming they, in fact, are victims."

Now, 27-year-old Harris is lashing out at the statement ... saying, "I honestly can’t believe what I’m reading."

"Black Lives Matter a hate group?! This statement and your whole press release at that is disgusting to read. RESIGN!"

Rapper Meek Mill echoed Harris' statement, saying "True colors.... welcome to PA!"

Harris isn't alone in demanding Gale's removal from office ... there's already a change.org petition calling for him to step down.
