Well, the parties switched plenty of times in the past, but Hilter was a socialist. Like he’s the best example that ‘working for the common good’ doesn’t mean you can’t be evil. He was working for the common good! of those he considered to be human. Which wasn’t most people.

Or maybe he’s a good example of ‘politics is more messy than left/right’.

A defining characteristic of the left is working towards a bigger government. It’s pretty much what originally separated the left and the right.
Any authoritarian regime, be it fascist or communist or something else, is inherently left-leaning on at least one of the political axes

Explain the following policies backed pretty much exclusively by right wingers in the modern day:

1. The government getting involved in whether women can have abortions

2. The government getting involved in whether gay people can marry

3. The government getting involved in what bathroom trans people go to

4. The war on drugs

These sure sound like bigger government things to me
