Avoid snarky comments.

Avoid namecalling.

Avoid "you bad, me good"

Stick to the issues.

Avoid responding to people who intentionally post dtuff to get a rise out of others.

I could have easily made a snarky comment about the issues I disagree with Palin on. For example I could have gone typical lounge poster and said "I disagree with her on teaching abstinence only, look how well THAT turned out for her daughter." But crap like that isn't necessary to get my point across. Nor do others need to do it.
