First of all, where are hearing tons of people attacking OC except perhaps in reaction to a few really stupid and even illegal events like happened in Washington that really have no more to do with OC than does yelling "FIRE!" falsely in a crowded theater have to do with freedom of speech?
Secondly, I think most all here recognize the various benefits of OCing including drawing a certain amount of enemy fire. The same is true for those who like military-style rifle platforms. Indeed, all who carry for self defense are drawing a certain amount of fire for those who don't care about that but really like to be able to go hunting.
The key thing is that we should not be dividing gun owners. If a few CC-only folks want to attack OC, that is unfortunate. But we should know better. Much good work has been done by those who have worked to expand who can get permits and where they are valid. Much good work has been done by those who insist on carrying without getting a permit. Let's stop trying to divide ourselves based on our favored carry method (of the day). We have responsible, law abiding gun owners, and we have criminals and morons
No further distinction is needed, please.
