As for "who is responsible?" - you mean for EXTREMISM? Can be asked on a number of fronts. ANTIFA and BLM included. A good point made by our side. And tossed aside by much of yours.
You gaslight like the racist rapist imposter we just kicked out of the White House, America’s biggest loser, the one losing the crime ring he has always pretended was a company.
You lie like a disgraced OSU wrestling coach worming his way into congress.
Antifa is still the official position of the United States military and every patriot in this country.
Why do you feel so inferior to Black people? Did you have it too easy in your bubble of white privilege?
