Something which many people could better understand is that just because they have an opinion, and they express it, and they believe that it is correct, that doesn't mean they are exempt from the rules. In fact, even if the opinion were
verifiably correct, if it were a breach it would
still be a breach.
For example: 'Ships have crew. Idiot.
'
Would get you modded. And that is factually correct, not just an opinion, but it still breaks the guidelines.
So, you can express your opinion - or even state facts, with citations if you'd like - in a way that follows the guidelines of the board, or your posts will end up moderated - regardless of how correct you feel that opinion is (or indeed, if you were stating a fact and citing peer reviewed journal articles, for that matter). Correctness isn't the metric. Respect for other members and staying on the right side of the guidelines and rules so that we maintain the atmosphere of the board is.
