I really, really try to stay out of meta discussions, because they just make me upset, but is it really SE policy to arbitrarily change questions that don't fit the site? I thought the policy was to close questions that did not belong and give the original author of the question the option to make the question better, which would allow the question to be reopened.
For instance, when I click edit on a question, the side bar displays the following text:
How to Edit
► fix grammatical or spelling errors
► clarify meaning without changing it
► correct minor mistakes
► add related resources or links
► always respect the original author
Note the bolded items. I think the existance of this meta post indicates that the original author was not respected and I personally think the question was actually changed, not clarified.
Also, I found this post on meta SO where Jeff says "never [...] change meaning".
So what is the actual policy? Should questionable questions be editted?
