And someone with a gun today ran into a school and shot six people. It is a fact that thousands are murdered by people using guns every year. Yet I think we can all see how completely illogical it is to declare gun owners as a whole responsible for this activity; indeed, that would be ridiculed and rightly so. You are applying precisely the same logic to Muslims as is used against gun owners by the anti-gun cheering section.
Then again gun owners aren't massing in the streets shouting "Death to All Non-Gun-Owners!"
You might see it that way, but to many anti-gunners, it's "gun owners" who are responsible for all of these mass shootings. Look at the way the most recent shooter's "interest in guns" is being played up in the media.
That is where this kind of thinking gets us-bandwagon movements that infringe on everyone's rights, instead of punishing those who are responsible for the crime.
