Whoa! Get off of your high horse for a second. This is not about gun rights, but about blame.
For the last decade and a half, we've heard a constant stream of rhetoric about Islamic terrorists. This meme was actually prompted by another Meme trashing Islamic terrorists. It points out that the problem with mass shootings isn't confined to one group.
My daughter recently received her CCW and doesn't leave the house unarmed. She's got me considering purchasing a weapon as well.
I'm pointing out that terrorism us not just some foreign people that have a bone to pick with America.
I would say the every mass killing in the US for the last century has one thing in common: mental illness. From the Bath Michigan massacre to Sandy Hook to yesterday's shootings.
SCOTUS, in finally making a decision on gun rights, confirmed there are two classes of American citizens that do not have second amendment rights: convicted felons and mentally ill. The NRA doesn't want to come up with a solution to refrain those groups from purchasing a weapon. Eben Adam Lanza, with his known mental problems, could have purchased a weapon, but instead, chose to use his mother's arsenal.
Now, in the cases I've cited, can you name one mass killing where the shooter was of sound mind?
That is the point.
