This is weird story.
If Scheer was asked a question with something to do with Nazis and he doesn't make a point to denounce Nazis, does that make him a Nazi sympathizer? How did this story get in the news?
Your hypothetical Nazi:
Nazi - "Because the Nazis were correct in their extermination of the Jews, shouldn't we have tighter border security to keep Jews out"?
Scheer - "Justin Trudeau's response to border security has been very weak. As PM, I will keep out all undesirable elements"Should sheer denounce Nazism in this hypothetical case?
The answer is a resounding and obvious YES!!! YES he should!!!
Scheer: "I didn't hear the Jew part...."
