Hard disagree. Particularly with "... makes any assumptions by your professor warranted."

A Professor of all people should know that assumptions are not warranted in this context, or most, really. Presumably, he does, as he asked to speak with OP.

I get what you're saying, guilty by association. I've always viewed the 11 nazi saying as more of -- the 10 people aren't necessarily Nazis, but might as well be if everybody they know thinks they are.

Pretty much agree with your post beyond calling an assumption warranted. That is bad.
