How Not to Be a Troll, a Guide:
1. Be clear & have a reasoned argument, position or query
2. Contribute something of value in at least one other thread before saying something likely to arouse controversy off-topic
3. Don't overgeneralize
4. If it's a question you're asking, indicate that you're asking a question
5. Be reasonably polite, and don't start off your LSD career by attacking individuals personally
That's pretty much it.
