Conservatives with ties to the NRA are looking for any excuse to keep the spotlight off of gun control.  Extra points for finding a good Christian evil to point the finger at.  So in walks Rep. Diane Black of Tennessee with a not just a theory, but an honest certainty about the root of all these shootings: Pornography!  I kid you not.  terms she’s attributed to the importance of Pornography as a motivator for school shootings are “Root Cause” and “Big part”.  Which makes me wonder…does she have any idea why people watch porn or what it’s for?  It seems to me that if anything, porn might have the opposite effect.  It certainly isn’t something known for winding people too tightly.
