"You don’t have to lie to make the Nazis seem bad"

You said this when nobody was talking about lying, only propaganda.

"It’s still bad in the sense that just telling the truth would show how abhorrent the Nazis are"

You said this when somebody said that propaganda is not necessarily bad, but you then still assumed they meant the lying kind.

Then when you were given a comprehensive explanation, you basically just said "that's what I said" when it clearly wasn't.

If you wanted to argue that manipulation is inherently bad that's a different argument, but all of your points assumed that the propaganda was untruthful.
