Neither of those threads, or the LGBT are exactly promoting a specific stand point.
They're all very general discussion about specific topics.
The Oubliette is one of the most mature boards I've ever encountered. Yes things occasionally get heated, but not flamey or troll infested. That's good debate right there. It's healthy discussion.
Coming onto a thread, and having your opinions challenged in a robust manner should be expected. Having experienced that and then wanting to get a thread shut down because isn't terribly good behaviour.
If you feel the discussion is pointless, don't join in.
