You expect more from a guy who calls himself Da Baby, and I expect more from members of my own family, despite having plenty of reasons not to.
Certainly, you don't expect them to slap the shit out of a woman while walking to the stage in a packed concert venue, where anyone could have been filming.
Not that my concern is that the incident was filmed, mind you. I'm officially against slapping the shit out of a woman, regardless of whether or not it's being filmed.
In general, I'm against any abuse that's not emotional in nature.
