The danger is that a flashpoint will come, that for example BLM will mob the wrong house in the wrong state and the occupants will open fire, leaving a dozen dead. The entire country would explode.

No it wouldn't. A lot of this analysis seems out of touch. In this scenario, 95% of the country doesn't read pass the inevitable fake news CNN headline and emails from your HR dept that read "A country mourns for the victims of another mass shooting: 12 peaceful protestors died at the hands of a white supremacist terrorist armed with an AR-15".

They can just make up whatever they want now and people will go along with it.
