No, but you ought to know what some of the ideas were; conversant does not mean expert. It's only really necessary to use the right vocabulary if you want to change any minds, but it's STILL better not to use words that are actively incorrect (and are also painfully simple and germain to the discussion).

If the point is just to be loud and obnoxious for people who already superficially agree with you, by all means, throw all this out: you can just be really mad about Hitler's treatment of Jews in focus camps while he was the leader of Poland.
