Mega Nazis, if they should come to exist, are going to seek to hunt people down whether or not anti-Nazis have done so first.
If you are concerned about Mega Nazis, hoping you can convince them to be tolerant Mega Nazis by the example of tolerant anti-Nazis is...not likely to be an effective approach.
Just cuz you're in lock-step with the zietgiest now doesn't mean you will be in the future.
