I feel pretty comfortable drawing a straight line between the GOP and the terrible shooting at the Planned Parenthood in Colorado Springs.
The GOP not only encourages  or at least makes common cause with  persons who view armed conflict as an acceptable form of social control in this country, but it has encouraged  or at least made common cause with  persons who characterize Planned Parenthood as an evil abortion mill.
Why should we be shocked that an armed, deranged person would stage a murderous attack on an organization that has been calumnized by the GOP and its fellow travelers.
This is not that last episode of this kind.
