There is, in fact, a good question wrt how much of NFA is actually constitutional. A funny thing about this is that ATF has dropped cases on several occasions where the defendant tried this angle, presumably because they didn't want something contrary to their current regulations as written to be overturned in court, and because they had plenty of other charges to throw at those guys anyway.

Given that it was modeled on gun control legislation from pre-WWII Germany, it's _not_ something which they want looked at too closely.

This absurd belief that "If the jews had guns they wouldn't have been genocided" is just that: Absurd and utterly unsupported by history.

Not only did jews have guns, but Polish jews had an entire military and state and that did not protect them.

Because guns do not protect you, other people willing to die for you protect you.
