Hitler exemplifies your last statement beautifully. The world needs people who stand strong with their ideas but constantly think about others and be open-minded. And not douchebags.
Pretty much everyone knows about the whole Nazi = bad thing. So, because so many people know about it, I'm pointing to an example where the original commenter's ideal behavior went wrong. Godwin and Glenn Beck just threw "Hitler" around to get a reaction. That's not what's going on here.
