It is if the person debating you says "Hitler was right wing" and you have Nazi quotes where actual Nazis, including Hitler, say they were left wing.

Is citing a NAZI ever a good debating technique?

Probably not. He said a lot of leftist things, and most leftist things are unhinged nonsense.

If you're citing about the Nazi-like actions or statements of a guy/girl trying to spread Nazi-like hate or agenda, YES! Problem is, MOST of "them" have never actually SEEN, or think what they see is "fake news" … stupidly … and have imaginary greatness in their small minds! Nazi-ism, (white nationalism) is NOTHING GREAT, other than a "great disaster"!

If the conservative Trump Party (as opposed to the Republican Party), win on Tuesday, I believe it will be the start of a horrendous "lesson" for them.

If you want to illustrate what a Nazi said, the. You have to quote them. If they are saying the same things we are hearing today, then perhaps you don’t know when you are quoting a Nazi.

If someone says they hate the Jews and believe the supremacy of an ethnostate, you will think that’s a new idea unless someone cites a Nazi for you.

Ignorance is not preferable.

What’s that old Jewish saying? “Make sure we forget” ?
