Kudos to them for their bravery. But from what I've read, I'd say that rather than most, the numbers probably were closer to 50-50.
In any case, there was no chance that a popular uprising could succeed, even if such a movement had been supported by 80% of the people. The methods used by the SS and the Gestapo to suppress dissent were simply too brutal, too ruthless and too effective.
Brutal,Ruthless and Effective,,,
Ultimately,
FAIL!
Actually popular revolution only take about 10% of the population. Most of the “people” are apathetic, old, government employees or just stupid.
Most of the population is unarmed.
Much of the population is unware.
But...show one video of the powers that be shooting into a peaceful crowd and you will change the world.
It worked in 1775 and 1970.
No, getting someone to stand in that crowd is the trick.
