You can post a thread here without it getting closed. You just have to, yourself, behave, and hope that everyone else who posts on your thread behaves. It is actually possible to learn from observation.
With the freedom of speech comes responsibilities. When a discussion degrades into personal attacks where the original topic is no longer relevant, usually due to two individuals hijacking the thread through personal attacks, the discussion of the original topic is overshadowed by the pi$$ing contest.
Most times I agree with closure, and as said; GT is privately held.
