It's a good point but the flip side is not every point in time is 1932 Germany.

How do we keep a democracy where ideas we don't agree with can still be implemented if there's a majority (assuming minority rights are protected reasonably well) while at the same time ensuring we don't end up with democracy being used as a tool to get a totalitarian regime.

For a more recent example we can look maybe at Türkiye.

Preventing ideas that are still within the boundary of a democracy from being implemented is not democracy either.

The US e.g. has a Supreme Court and a constitution. Presumably as long as that court is functional and the constitution is applied then all is good?

Unfortunately I'm not familiar enough with Germany's fall into fascism and whether there was some sort of watershed moment where it was clear that something was broken and could still have been remediated.
