What you need to understand is that this thread isn't actually about an MTV video. What's going on is that online bigots have been looking for an way to get rid of all discussion of social justice for years, so they're trying to hoodwink Democrats into thinking that social justice issues are why they lost this election, when there's no evidence to support that, as an effort to get Democrats to stop caring about minorities.
There's a difference between promoting social justice, and being a "social justice warrior" IMO.
