Sugar Bear was polite but clear ... he's not happy that Mama June allowed a convicted child molester to get his hands on his daughter.
TMZ posted the pic of June on a staircase with Honey Boo Boo and Mark McDaniel -- the man who molested one of her other children. McDaniel has his hands on Honey Boo Boo's back.
Sugar Bear was measured, but made it clear it was not cool. He's also upset the show was cancelled.
