OK, so the electoral college is largely a product of the 3/5ths compromise on slavery. Should it have been removed when slavery was made unconstitutional? Should inter-racial marriage have been legalized then? How about restitution to former slaves? Was "separate but equal" constitutional?

Well, let's see, we could take the model of Switzerland, where everyone and their dog has a gun, and ammo is sold at cost, but to buy ammo you either have to (buy & use it at a range) or (register the sale with the government). Could we legally require that in the US? Could we require a national registry of every gun owned in the country? Can we restrict children from owning guns? How about criminals? Felons? Violent felons? How about people who've threatened the president?

Are you really saying that this is sufficiently clear in the original text? Because half the time I can't even figure out what an individual FF would have said, much less what the lot of them would have agreed to, much less whether I agree with them.
