I think the essay is right on target.
It's nice and fuzzy to think that the NRA and anyone with an (R) after their name is looking out for your best interests, including your gun rights, but it just ain't so. It's also nice and empowering to think those dirty liberals are doing whatever it takes to tear down our nation, but that also just ain't so.
The fact is, politicians and political groups can and will prey on your fears to pad their bottom line. This isn't to say they don't so some good--I think the NRA has done a lot of good. But they do employ fear-mongering, and they will take your money hand over fist no matter what the current political climate is.
And you can say Obama is anti-gun all you want, but the only "proof" you have are second-hand whispers and conjecture. His legislative record actually shows neutral and gun-friendly actions. Not saying he might not do something next term, but a giant green gorilla might fall out of the sky and *** you up the *** too. Wanna worry about that?
Like all things in life, these issues aren't black and white. They need to be taken with a grain of salt.
