You lost, you can make up all the excuses you want. You still lost. That was also when there was actual parity between the north and south. It would be an absolute curb stomping of epic proportions if it happened now.
This isn't a street fight where being less educated and poorer gives you some sort of advantage.
Money goes a LONG way in a war, which is why the US spends so much money on our defense budget and the north has a **** of a lot more of it than the south. We would be rolling out planes and tanks while you guys are scraping together enough money to buy another AR.
The fact that you think southerns owning more guns gives you some sort of advantage is also laughable. Do you realize how much weaponry is stockpiled by the NYPD, CPD, and the other big cities in the north? Do you realize how easy it would be to buy guns for our soldiers if a war kicked off?
I have shot guns since I was a kid and have a gun collector license. Getting someone competent enough with a firearm to trot into battle is not all that difficult. Why do you think firearm competency is not one of the main criteria for SF testing? Because you can get someone competent real ******* quick if need be.
I am not even going to get into the massive advantage we have of all the high powered execs, top engineers, top doctors/surgeons, etc. that would really swing the war even further into the Norths favor.
