Common courtesy? You mean like deciding a man is guilty of murder, without bothering to learn facts? You mean like putting a $10K bounty on his head? Common courtesy went out the window a long time ago. Go back and read your first post to me. You started with an attack. You might find that when you talk to people respectfully, you're more likely to get it back.
Why should you have to do the heavy work?

You mean learning something on your own? I don't know. That really does seem harsh, doesn't it?
