Read "The Coming Of The Third Reich" by Richard J Evans to see how a very liberal democracy (Weimar Republic) was undermined:

1) No strong sense of "norms" in the culture

2) Manipulation of "Free Speech" into "Equal Speech"

3) Manipulation of a populist movement entirely built on nostalgia, the-jews-backstabbed-the-kaiser mythology, and "Germany First" so that they were far enough from Hitler that he could claim to not control them directly, but everyone else feared touching him would start a nationwide riot.

4) Political violence was normalized

5) Everything (churches, tennis clubs) had political party variants (ex: the socialist democrat Protestant church vs a communist one)

6) Terrorist attack on the Reichstag was a huge opportunity and turning point

There's a world of difference between the Internet of 2017 and Germany of 1932 that I really do suggest keeping them apart, and pick up the book.
