You really think Trump can incite a race war? You really think the people who spend their time being offended for everyone else is going to do more than the whole bunch of nothing and clogging of social media they already do?
Aside from the few morons left in Antifa and the -brained white supremacists, no one isn't going to do anything. If there isn't time to take a selfie, there's not a lot of interest to do anything that takes actual physical effort. It's the ing United States where cognitive dissonance is a past time.
