The man has been paid to have an honest gauge on uneasy situations -- legal, ethical and otherwise -- and according to Hizzoner, he rules that all this mud-slinging stinks. On Friday, Mathis held court on his IG page and called for an end to the recent missiles launched in the public eye amongst Black entertainers.

He didn't single out Katt and Mo by name but the social media space has been in shambles since Katt's interview aired on January 3 ... and Mo followed suit this week -- even joining KW's nationwide tour with other comics who seem to have bones to pick.

Judge Mathis didn't bite his tongue -- he called the feeding frenzy an embarrassment to Black culture and feels it his gut that big H'wood execs and studios are silently laughing on the sidelines.

He also pointed out he doesn't see other cultures tearing each other down in public ... just Black people being the sideshow spectacle -- that's how's he framing his argument here.

The 63-year-old justice admitted he doesn't always keep his cool in his own courtroom but notes those outbursts are spun into entertainment for his TV shows.

Judge Mathis concluded by stressing that these stars' issues should be hashed out in private settings ... instead of setting bad examples.

We'll see if Shannon Sharpe takes a breather with these interviews -- or if he keeps on bringing celebs with more grievances to air. On its face, he seems inclined toward the latter.
