Personally, I love the people who will, instead of typing out "Strawman!" as a response, find a picture of a strawman and just use that.
Still not as bad as the "I don't want to live on this planet anymore" picture. Do people honestly not realise how childish it makes them seem?
"Those people have views that disagree with my views? I DON'T WANT TO LIVE ON THIS PLANET ANYMORE!"
But to be fair, searching for meaningful debate on the Internet is like trying to find haute cuisine at a McDonald's (no offense intended to McDonald's... I loves me some Chicken McNuggets, pink slime and all).
There's a big difference between someone interested in a discussion or debate, and someone who just wants to be right and let you know how right they are, and it's nearly impossible to discern between the two at a glance.
"I don't want to live..." and to a lesser extent the Willy Wonka meme are quick shortcuts for those who have no real desire to explore or expand their ideas, but would like you to still know how much smarter they are than you, you Internet TOOL.
I work with a person (exactly ONE) that disagrees with me on just about every fundamental political, societal, or religious ground, but I can't hate him because he is always willing to listen to me talk, take me seriously, and talk back. We aren't friends and never will be, but I get a lot more out a conversation with him than I do looking at Failblog or Memebase.
I'm perfectly happy living on this planet, after all.
EDIT: Though I am willing to admit that I have a bad habit of confusing "analogy" with "straw man" when arguing with people... it's not fair, but I do so love a good analogy (After all... I compared people to Chicken Nuggets above.)
