I suspect they want to encourage the division and they are hoping some of the gagged and marginalized citizens will resort to violence (as that is pretty much the only way they will be heard a this point).
All it takes is a handful of nutters (maybe even being egged on by undercover agents) to set off a bomb somewhere. The following days will be filled with reports on the danger of white supremacist domestic terrorism. The following weeks will be used to pass far more draconian security laws than they did after 9/11. Government power will increase exponentially. The people will have no privacy, while the government will be mostly secret. The playbook is fairly well-known, and Americans seem to be happily walking into it.
