Meta (my own personal definition) : Discussing characterization. The reasons behind a character's actions, thoughts and what makes them who they are.
1. NO WANK. Just like Starfleet we are a "peacekeeping armada."
2. Discuss. Don't argue.
3. If all else fails, agree to disagree and play nice~!
Also if anyone has a topic they would love to have up for discussion, suggest it here :)
