I do not agree with the NRA's methods or stance. They view any effort to moderate anything to do with guns as an attack they have to meet with the full force of their political power. I understand why they do it. They believe, rightly so, that equally rabid forces on the other side of the argument will not stop with just "reasonable" laws regarding guns, they will press on for a full ban of everything. So the NRA cannot afford to let up at all and must treat any attack on gun rights as the enemy battering at the gates.
This goes to my point on the above tweet from CBS news (which is total horseshit). If both sides were willing to be moderate, a lot more could be done. But since neither side will relinquish their totally extreme positions, we will get nowhere.
