T.I. has really been putting his classic braggadocio Atlanta trap music to the side recently, and no one’s really complaining.

That’s because he’s using his voice to bolster the #BlackLivesMatter movement. Coming off an incredible BET Hip Hop Awards performance where he performed “We Will Not,” his new anthem representing the plight of inequality and police brutality occurring daily, Tip is making sure everyone knows where he’s coming from, even if that means calling out Floyd Mayweather.

Taking to Instagram yesterday (October 12), T.I. unloaded on the championship boxer after he made some pretty eye-rolling All Lives Matter comments.

“Yo, @floydmayweather all our past personal differences & opinions of each other aside.... This is socially irresponsible,inconsiderate,& insensitive. It mirrors delusional oblivion in a way only brainwashing tactics can achieve,” he captioned under a video repost of Mayweather’s comments. “This completely undermines & discredits the movements that fight for the plights of our people. You're a leader whether you know it or not. Don't get so lost in personal possession or individual achievement that you lose sight of the things that are larger than all of us.”

Mr. Harris then continued in the rather extensive post with a little history lesson. Let’s just say we’re here for it. “Freedom, equality, justice, human rights,qualities of life that have been withheld (or given out sparingly) from our people for generations (400 yrs approximately)," he explained. "Either you're the oppressed,or you're the oppressor. What side would you like to believe you're on? While some will try to make this more critical than I hope for it to seem...it must be said. The world is watching. I have an obligation to myself & those who follow me to address this. Just know I ain't looking to clown you,I'm just trying to enlighten you,hoping that with better insight you can use your powers for good. Respectfully...-King #USorELSE.”

The point Floyd Mayweather was trying to make seemed a little shallow and his assertion that people are using the hashtag to be trendy rather than incorporate it into their lives and push for progressive change is a little cynical (and frankly, wrong). To each his/her own though.
