One sees that these guys, who have always been paranoid, are now feeling seriously threatened.

They see that a lot of politicians, previously cowed by the NRA, are starting to stand up to the gun lobby.

They are not used to that, and considering the NRA logic of “just because Obama did nothing at all to restrict access to guns in his first four years does not mean he won’t be coming after them in his second term”, it simply confirms their paranoid delusions.
