Two things I want to raise:
1. The number of deleted or "moved" threads. This is appalling. For a forum that purports to represent free speech and discussion of political issues and news/current affairs issues I find it a bit strange that, even though the person was very poor at expressing their ideas, they were not given a chance. You might say "but the thread was active for X days", but I believe that this in itself is not adequate, issues do not expire after 30 days or so, they are likely to be there for a lot longer and should be discussed. Threads should not be shut down, in my opinion, even if people begin to abuse each other, and this brings me to my next issue.
2. People should not be prevented from expressing ideas but should be prevented from personally attacking their fellow debaters. Swearing and personal attacks, I believe, are not right when discussing and debating issues of significance. I agree, these sort of posts should be regulated or edited - but they should not and neither should the threads they're contained in, be outright deleted. No matter how controversial the issue, argument or debate contained in a thread, it should not be deleted but those who decide to swear or launch personal attacks against other debaters should be reprimanded in some way.
A clearer outline of the acceptable/unacceptable elements within the thread should be developed rather than the simplistic "I'll keep this organised simply by stickying/unstickying and deleting irrelevant or abusive threads. If you have any concerns PM me or post in this thread" edict issued by one of the moderators of this thread.
The area of politics, news and current affairs is very, very delicate. People have many conflicting points of view and conflicting ideas in regards to the issues that contemporary society raises. If you are going to devote an entire area of the forum to it, you should create a sensible set of rules to regulate the forum so people do not get unruly and out of hand but still making sure that no matter how "extremist" a point of view, it's still heard, explored and debated.
The exceptions to that are obviously rude, racist and sexist (etc...) viewpoints that our Western society should not entertain (unless they cause a massive uproar...)...
