This is a decent and sensible question IMO, barkingcat (downthread) provides a reasoned answer that seems to fit, but the question is good .. so why did the person feel the need to use a throwaway, and why is it downvoted. Unlike other questions it doesn't appear to be the sort of thing one ignorant of the answer could readily google for.

I know, we're not supposed to complain about downvotes but it just makes me sad that we - as a community - don't value honest questions.
