Blacks Students Dragged Off Stage Because Of Racism, Or Because They Behave Absolutely Terrible?

What's really going on here? Are the asians or whites acting like these black students? Isn't this ceremony supposed to showcase at least some sort of dignity? What's next? Black students twerking on stage? And what's going on with them when they are thrown off stage? They seem to be in some type of trance? They don't even seem to notice that someone is throwing them off stage? Are they not able to control themselves? Are they spontaniously bursting into wild uncontrolled dancing?

Perhaps you have to be completely disconnected from the real world in order to celebrate the fact that you just got a totally useless degree and 100k student debt?
