"The trouble with fighting for human freedom is that one spends most of one's time defending scoundrels. For it is against scoundrels that oppressive laws are first aimed, and oppression must be stopped at the beginning if it is to be stopped at all." - H.L. Mencken

I would agree that it's not the most wholeheartedly positive example, but I think it's one of the most honest examples in a sense if you really want to evaluate anonymity on the internet in context and show the bad with the good.

Excellent Mencken quote. Another relevant one: "Man is least himself when he talks in his own person. Give him a mask, and he will tell you the truth." --Oscar Wilde

I've sometimes wondered what Mencken would have thought of the internet.

Especially given that large parts of his life could be plausibly summarized by "he did it for the lulz".
