Here's how it works.
The govt. tells you to support nazism
They promote widespread shows of approval for it
If you're living in Germany, you will not stand against them because who's to say even your best friend, whom publicly is so pro-nazi, wouldnt turn you in if you confided in them your hatred for the regime.
Also, almost immediately after the Nazis came to power they began crushing all opposers. There was a group of students in the early 30s who were printing anti-nazi leaflets and giving them around....cant really remember what they were called..."White rose" or something. Anyways, this group of 20 year olds was entirely executed.
