Mom Makes Kids Fight [VIDEO]

This may be shocking to some, but I'm not surprised. The video you're about to watch shows two very young toddlers fighting each other with the mom in the background encouraging the fight.

On the surface this seems deplorable - however, I've witnessed many, many, many times - parents telling a younger sibling to hit their brother or sister back after being bullied or hit by the older sibling. Could this be one of those moments? And if so, is the mom doing the right thing by teaching her little girl to fight back? Do you think it's a good idea for parents to encourage "hitting back"? Or are you a proponent of "go and tell someone, don't hit back"?

Also (after you watch the video), do you think DSS (Department Od Social Services)/CPS (Child Protective Services) should get involved? (comment below)
