The govt already funds groups that fight White Supremacy - they are called the FBI and DOJ. When laws are broken by these white supremacist groups - or anyone else - the FBI, DOJ, and state and local law enforcement groups are supposed to step in and do their jobs - arrest / indict / charge / convict them for their crimes.
Last I checked they have not been de-funded.
Meanwhile, in Va, the police, Mayor, and governor failed to plan / prepare / prevent / protect / enforce the law. While 3 people were being murdered and dozens injured the police safely stayed behind their barricades and WATCHED as the violence unfolded and the crimes were committed.
McAuliffe, like you want to blame the President for what happened. Of course McAuliffe also declared the police - who did nothing while 3 people were killed and dozens were wounded - 'did a great job.' Of course McAuliffe immediately after the event began pushing his Anti-Gun agenda despite no gun having been used during the violence.
