There's a really incredible book called Defying Hitler which is the memoir of Sebastian Haffner in the lead up to the Second World War in Germany. It tells the story of a guy who is growing increasingly uneasy with the situation in Germany, and how the growing Nazi regime (after 1933) changed the lives of him and the people around him. It gives a good look into how people talked about what was happening around them.

One of the most striking things that I noticed, was that there was a general uneasiness, but individual people didn't really choose to openly acknowledge it. Most people who didn't agree with what was going on just didn't show up to political events, almost like they tried to ignore it. There was also an air of general acquiescence, almost as if people grumbled about what Germany was becoming, but let it happen. Defying Hitler, in Haffner's mind, was not allowing himself to fall into that kind of acquiescence. He felt he couldn't openly defy the state, but he could do so by acknowledging what was happening around him, and choosing to not letting himself slip into a state of apathy. I'd recommend reading it if you want to learn more, and its a pretty easy read.

EDIT: Keep in mind, this is a single perspective. I can't give you the broader information about how much this happened, how many individuals felt this way, but it does give you an example, and a glimpse into how more people felt.
