For all of the railing and teeth gnashing that's went on, I haven't heard one mention of anyone actually OCing a long gun other than the OP's sidekick.
Surely the staunch long gun OC advocates must, and on a daily basis.
You do not have to have a gun to support those that do.
You do not have to carry a gun to support those that do.
You do not have to OC to support those that do.
Etc. Etc.
