I wasn't the one who brought the Warsaw Jews up. It's not my fault if he uses poor examples to support his point. I used the most charitable interpretation of what he might mean by citing the Warsaw uprising: assuming it was supposed to be a contrast and not merely a redundant repetition.
"The gun-owning Jews of Warsaw can hardly be compared to gun-owning Americans of today. They didn't have 'black guns', they didn't have scoped deer rifles, they didn't have mountains of ammo."
They didn't have tanks, and planes, and artillery, etc, etc, etc. And neither will we.
"Above all, there weren't 80-100 million of them!"
Which is itself immaterial, because there will never be 80-100 million Americans in arms against their government. It's a matter of will to fight, not access to firearms.
Note that in this Warsaw example, we've once again switched from a domestic tyranny scenario to a foreign invasion scenario. If a totalitarian government ever comes to power in the United States, it will be by imposition from a foreign power...or with the support of the majority of Americans, just like it did in Hitler's Germany. Which is why some of us recognize the real solution is proactive and preventative: winning the cultural and political battles.
OK... Then what percentage of that 80-100 million do you suppose would have the will to fight a tyrannical government? 10%? 5%? Let's say that it's only 5%. How do you suppose the government with it's 1.5 million or so active duty personnel would do against 4-5 million heavily armed insurgents; many with military training? The planes and tanks you seem so impressed with aren't very useful in urban environments. The fight will be rifleman versus rifleman. There just aren't enough available to the government to deal with an insurgency of that magnitude.
