I completely agree with your sentiment, but privacy is a bit harder to sell--guns are badass and cool to collect, privacy is geeky and suspicious. Another key difference is that the second amendment is big business (Smith Ruger & co stock went up >500% during Obama). There are big businesses that could get behind anti-encryption, but mass appeal is more difficult- perhaps at least until something spectacular happens.
Second Amendment supporters are often interested in the Fourth as well; I think you would find a very solid group of them (particularly those who concealed-carry, rather than just hunters) are strongly opposed to this sort of thing.
Right. I live in Oklahoma which has...a strong 2nd Amendment contingent. The OK state government is taking a lot of heat from the federal government for refusing to implement the Real ID requirements for state DLs.
I'm not a conservative, but I can see the reasoning behind it: they know very well that this is one important step towards building a national database of personal information (or more likely, augmenting one that already exists). Actually, I have found more on the right concerned about privacy, government surveillance, etc, than on the left because this concern naturally meshes with the right's "small federal government" stance.
Remember how Social Security numbers were "just for Social Security -- not any kind of personal identifier"?
But perhaps the left, which has just as much ability to be hypocritical as the right, will see the light starting...oh, say, 12pm on January 20.
Agreed that there is a spectrum of second amendment supporters even amongst my acquaintances. "What should be do about Snowden?"is a conversation that can be fun to start over beers with mixed company.
