Yes, I did, and yes, you are right. It was amazing to watch a seamless transition from ammo shortages to the sort of weird class analysis indulged in by urban pseudo-intellectuals concerning small-town Western citizens, to the conclusion - entirely unsupported by any evidence - that racism was involved. It's really too bad, too, because clearly the author had access to data that might have led her to conclude that her invariable narrative was badly flawed.
I lose patience with this sort of determined refusal to see the nose before one's face. This was written to reassure New York liberals (1) that Western people are ignorant, paranoid racists, (2) that they are too unstable to be allowed to possess firearms, and (3) that the only sanity to be found in modern America is the bigoted narrative presented in such urban-centric fishwraps as Mother Jones. They lost an awful lot when they fired Nat Hentoff. Integrity, for one.
