If you have a country where half of the population disagrees with the other half, and each half "cancels" the other and refuses to do business with them, the country will grind to a halt.

But we are all witness to the fact that it doesn't, at least so far.

The reason why it does not is that people don't typically wear their politics on their sleeves though the divisive nature of present day politics is not helping with that. So in fact, you may be prophetic, time will tell on that one.

Do you live in the US? It's absolutely happening. The acts of open warfare, with actual politically motivated killings, are surging.

Saying it's not bad because it only happens to people to assert their Constitutional right to free speech is, besides not true... Orwellian.

Life in the US is fine. I have no idea what you're talking about. I have lots of friends saying controversial things on Twitter and social media and they're not only alive but have fulfilling and happy jobs.

> 43% of Germans voted for the NSDAP.

You are aware that they only reached that number after placing armed guards at the polling places, with large parts of the opposition in prison, missing or exile? Hitler wanted to win that "election" with a majority by any means possible, getting 43% despite all the steps he took were a slap in the face.

Then go back a year to the election of Juli 1932, before the NSDAP got into power. Despite Nationalsocialists and Communists battling it out in the streets, the voter turnout was very high at 84.1%. The NSDAP doubled its previous result and became strongest party at 37.3%.

And by the November elections that same year they had already lost several percent.

Paradoxically Hitlers campaign at that time ran less on antisemitism and more on restoring law and order as well as fixing the economy. Communism and the near endless pool of unemployed it could recruit from was the great enemy of the moment.

Treaty of Versailles caused this. If NSDAP didn't happen, some other extreme would.

That's a hell of a controversial claim, it's still pretty hotly debated among historians. You could perhaps say that people used the treaty as a scapegoat, but as for Versaille being the actual cause, not so much.

I think it is an attempt at something approximating a reverse Godwin.
