I think it's interesting to think about how to deal with posts like this one. The OP is clearly both wrong and opposed to being set straight, even by the simplest and clearest of reasoning. Should such posts be systematically ignored, or will we be required to always try to respond?
If we do systematically ignore wilfully ignorant OPs, we save our time and sanity, and in the case where the OP is just trying to pick a fight/spread FUD/manipulate the market we have denied his attempt.
But the drawback of ignoring such OPs is that a malicious OP can try to use it as "evidence" that he's right, that there's no answer to his FUD or that the community is rotten, a cult and so forth. Also there will be some rare cases where OP is honestly confused and can actually be set straight by extreme repetition.
Maybe if posts could be down-voted into invisibility at the top level we could gain the benefits of the the ignore, while avoiding the costs (the posting isn't much 'evidence' if no-one can see it). As it stands now it's enough for the OP to post another response for the posting to jump back to the top of the forum even that the overwhelming consensus is that it's noise.
