The point of these forums? No, not really. Discussion and debate, certainly - but I think it's bad form to continually rebuke other people if you've made your own opinion known (multiple times). People are always going to disagree with you (the general "you"), and you can confront them 24/7 and they'll still do it, they'll just move the conversation elsewhere if you won't allow them to state their own views in relative peace. Given that this thread exists to consolidate threads and posts on a given topic, it necessarily needs to allow multiple points of view to co-exist peaceably, even if they don't necessarily agree with one another.
Opinions are not sacrosanct, but neither can they be judged objectively due to their nature as opinions. People aren't required to defend their opinions in order to have them, nor should they feel forced to unless they wish to. I hope this is not your actual aim here, as opposed to reasoned and civil discussion and debate at the topic at hand.
