This argument is a symptom of US brainwashing and only a symptom of US brainwashing. There are three positions on any hypothesis:- convinced of falsehood, convinced of truth, or undecided.
If you cannot take a clear position on a hypothesis, you qualify as undecided.
However the real bugbear here is that peoiple can't see that some arguments overrule others. For example, my usual argument is that 911 is an inside job, and its quite an interesting argument to use as a model.
In this debate, for example, the best argument against the hypothesis I have heard is that "someone would have leaked the details of the crime" Now this sounds likely at first hearing. But then there's the forensic evidence that explosives were preplanted in all three buildings, which is conclusive and forensic.
That means that while I accept the fact that one of the US govdernment's key difficulties would be how to stop core insiders going public on the issue, the fact is that they DID manage to stop the core insiders informing the public, and we know, because we can see the evidence for explosives at ae911truth.org and the journal for 911 studies..
Now, this is all well and good, but pretending that because I accept the government would have had to pull off some skillful bullying/bribery/ media manipulation to manage to keep your average dumb American comfortable in the belief that 19 Arabs did it, does NOT mean I am arguing both sides.
It simply means that we have something else to work out a rational theory for, given the proofs.
To "argue both sides" on a subject like this doesn't demonstrate "neutrality", but BIAS IN FAVOUR of the official hypothesis, because you either reject, or are ignorant of, solid physical evidence disproving that theory.
In conclusion, arguing both sides when one side has presented compelling evidence is NOT neutrality, it is, instead, intellectual insecurity in the quality of your own judgement and convictions.
Or in the words of the debate: "lack of opinion"
