An ugly week, with the pipe bomber targeting Donald Trump critics with 13 bombs, a Louisville shooter who gunned down two black forks at a supermarket and the ugliness in Pittsburgh against Jews with 11 dead. Donald Trump only takes credit, never blame, though his influence is hardly deniable at this point.
Each of the three instigators of this week's violence were angry white nationalists, killing people who are not from the same 'tribe' as they were. In truth there is only one viable 'tribe' these days. It's called the human race.
