I think the answer is yes.

Is the NRA Encouraging Anti-Government Extremism?

Apparently the actions of National Rifle Association member Timothy McVeigh didn't teach the organization that its violent anti-government rhetoric can have dangerous consequences. On a day when thousands of Tea Party activists are taking to the streets to protest Tax Day, the Violence Policy Center has released a report today chronicling the increasing ties between the gun lobby and the Tea Party movement, and the NRA's adoption of much of the "Patriot movement's" anti-government language. The center sees direct parallels between the NRA's current activities and those in the years leading up to McVeigh's fateful decision to blow up the Oklahoma federal building:

"The gun lobby is once again embracing—and, equally important, validating—the anti-government rhetoric being offered by activists that range from Tea Party members, through pro-gun advocates, to members of the militia movement. And as was the case with Timothy McVeigh, the risk lies not so much with the organized members of these groups, but with the "lone wolves" who not only embrace their rhetoric, but are willing to act on it with violence."
