Every time someone argues something and uses the term Nazi or Nazism as a pejorative to emphasize their argument, they come across as a complete idiot, and even if they are right, I find it hard to believe them because of the ignorance they have shown.
You didn't live during the Nazi era, neither did I, but I'm sure that whoever says this hasn't even spent 100 hours of their time studying World War II in depth.
The Nazis were bad, of course, like any government, they did bad things... of course, they dropped two nuclear bombs on civilians.
Before, the Japanese were very bad, and now they are very good. Have they changed so much?
Before, the Jews were very good, and now they are very bad.
Think a little before you speak. Neither the bad guys are that bad nor the good guys that good.
If you're a Bitcoiner, don't use Nazism to strengthen your argument.
