Oh wow, I see how you moved the goalpost.

During a war a country kills. So now you moved the goalpost from claiming that the NSDAP was persecuting its own population to then claiming that it was killing its enemies. Like everyone else. Who started exterminating civilians first? Britain. Even if you believe in the holocaust there is absolutely nothing special about it.

Generally speaking wars are when governments do most of their killing.

Not true, the Bolsheviks killed at least 20 millions of their own people during peacetime.

it's also equally silly to think an authoritarian regime wasn't killing people at all within the country.

Like who? How many? I even gave you an example that proves that the NSDAP was not killing not even communist revolutionaries.

At the very least Nazi eugenics pushed for euthanasia of the "unfit".

Hahah oh god the goalpost has been moved again! I'm in favor of euthanasia so I don't see what's wrong with that.

Hitler also purged party leadership that he thought were unloyal.

The only ones he purged were a handful of people who were about to start a coup that would have led to countless deaths. That was a one off event, and it's pretty common to give the death penalty for high treason. Even the US has it.

But the Third Reich was not persecuting its people. Unlike the current governments of the West.
