Not quite half - 43.9% in 1933, and that election is not considered by historians to have been anything like free and fair. In the prior two elections, the Nazi share of the vote had decreased from 37.3% to 33.1%, indicating that Nazi popularity was on the decline. If it weren't for undemocratic backroom scheming that handed the chancellorship to Hitler, there might never have been a Third Reich.

So yeah, I think Zuckerberg's statement stands up well even in the face of 20th century history.

In 2003, 15000 Baath Party members were dismissed from their posts in Iraqi government ministries because of their 'evil' political affiliation.

Within two years 9000 of them had been rehired to try to repair the damage that their dismissal had caused.

Sometimes one just has to be pragmatic and put subjective opinion aside. Such tolerance doesn't equate to approval.

I don't think there's any ambiguity that Peter Thiel, the subject of this article, is approving Trump, and not just tolerating him.

Do you think firing nazis from their jobs would have worked? That would have been a bloodbath (more so). Even if it wasn't it would have played to the persecution complex.
