How did post-WWII German society handle people who had been ardent Nazi sympathizers?

by 1714alpha

Did the people who had been proudly flying the swastika flag mere weeks earlier just shut up and pretend it never happened? Did the rest of society just assume those people and their sentiments were gone? How did Germany make sure those supporters were no longer a threat to an open, free society? I'd also be interested to learn about the differences in how these people were treated differently in East and West Germany.

I ask because this is totally a thing that has never happened again, and we would never have another instance of a huge, powerful society fractured by a large segment of hateful fascists. Nope. Not fascists. Ahem.
