At some point in any rational discourse, all analogies become tortured analogies. The trick is in not focusing on how the analogy is wrong, but in what can be improved about the underlying idea. By all means, cast the analogy aside, for it is worthless on its own. It is only a means to relate to or understand the underlying idea. Any time you feel inclined to dig-in and tear apart an analogy, it's wise to consider whether you're contributing to the refinement of the underlying idea, or just bikeshedding.
