Of course not. I understood your comment to be questioning whether there exist any individual Americans who condemn Snowden and proposing as evidence for their non-existence "Everyone American I know". If you were just saying that you don't think the majority of Americans condemn Snowden then I have no disagreement.

I was disagreeing with the premise that all Americans think exactly the same thing by presenting any example of Americans who disagree. Since I know quite a few, it's at least enough that you can't say "Americans think X," which is what the post I replied to said.
