unless the person is undeducated and doesn't know much about the gun debate

First off, background checks were required after the 1993 brady bill, not the 1968 gun control act.

The 1878 case the gentleman mentions which IIRC is Hutchinson V state explicetely said that open carrying of a firearm was constitutionally protected, not concealing one.

the 1934 National Firearms Act did not control "bushmaster's of yesterday". It controlled machine guns, and short barrelled long guns. Guess what, the tommy gun was a machine gun in 1934 and it is a machine gun today. Also, it is easier to argue that machine guns back in the 1920's and 30's were not a common weapon found in households. The same does not apply for semi-automatic weapons today.

It's one thing to ban weird, uncommon weapons and say "hey, it didn't really affect anyone". It's another thing to ban the most common firearms being sold today- you can't say "it's not going to affect anyone".

The problem is the false equivalency- that the gun controls of yester-year were okay therefore by default the ones today are.
