Both sides didn't start the shooting. The other side is just now firing back.
What we are seeing now is a response from those that have seen the Constitution trampled in a mean spirited way. Obama himself called the Republicans "the enemy". No partisanship there. For the last 8 years that's all it has been.
So now it's both sides? Ok.
I certainly hope you are not trying to use the childhood "yeah, but he did it first, mom!" argument.
I don't know about you, but MY mother never let anyone get away with that nonsense, and I don't have any friends who's mom allowed it either.
