Yeah, when Em made his first little comments, like "Oh, I wanna take Christina home" or "I wanna have a threesome with Britney and Christina"-that was him being cute. But when he insulted Christina, talking about rumors he knew weren't true to say she was a slut because he was mad she called him out on Bonnie and Clyde... That was out of line, and when she confronted him about it, and told him why it was important to speak against DV because of her past, they hugged it out. We know he reacts off of his emotions, but I think he also knows when he is wrong. I think when he is confronted by a woman saying "That's wrong" he understands, I mean, he's smart enough to understand. We also see he can express regret and grow now. So I don't think he'd mind us criticizing him like this, because I think he cares now and would want to be a good man. (Also, I'm just glad you brought up Tina, because her, Mariah and Bey are my girls!)
