"The average Muslim =/= an ISIS extremist. Why is that too hard to understand?"

Oh good argument, let me try:

"The average Nazi =/= soldier/killer of Jews. Why is that too hard to understand?"

"The average communist =/= Khmer Rouge or FARC fighter. Why is that too hard to understand?"

Won't somebody think of the "moderate" Nazis and communists?

I mean, I thought sane people judged an ideology by two things: its leaders, its doctrines, not by the masses of followers some of which may or may not be devout, may or may not be just naive useful idiots who don't realize what they're actually supporting.

Moderate Muslims are NOT in any way shape or form proof that Islam is a peaceful religion any more than moderate communists (many of which you can probably find on any college campus) or "peaceful" Nazis (not even neonazi actually goes out to kill black people, many are just superficial nazis who think it's "cool" to be one) are proof that these two ideologies are benign.
