"Of the 85 deadly terrorist attacks in the United States since 2001, 73 per cent were committed by far-right extremists, compared to 27 per cent by Islamist extremists."

This is the ugly truth that the far-right refuses to acknowledge: they are far more dangerous and destructive than the Islamic extremists. 

And this fact illustrates the bone-headed stupidity of Trump and his supporters who believe that building a wall and closing borders to immigrants will reduce terrorist attacks in the United States. 

A far more intelligent decision would be to build a wall to keep NRA lobbyists away from members of Congress.
