I think their concerns are legit. It's one thing to have various factions or members of Congress talking about gun control and citing false statistics in the aftermath of shootings. Quite another for the president to do so.
OB is a whore just like any. he can talk all he wants, until he actually does something, there really isn't too much to worry about. I think he also understands that there isn't much you can do, and most of what people seems to suggest wouldn't prevent mass shootings in any way.
Maybe you're not seeing masses of conservatives leading the charge on "practical reform," because they believe the laws on the books should be enforced and they see the same kinds of problems that many reasonable people see with effectively trying to disarm segments of the population. And maybe their fears have not been realized because they have effectively lobbied to prevent laws from being passed that would not prevent mass shootings, but would interfere with the Second Amendment rights of many.
Whatever the case is their message isn't getting out. they need to repackage it.
Overall, I would not dismiss their concerns as cavalierly as you have.
I do, i think its ridiculous. Now that may change soon. but for now, this is what i think.
