Each to their own I guess.
EDIT: My point is that it's a bad metaphor not because there are no links between the two but, as with most heavily emotive metaphors, it comes with too much baggage which distracts from the intended message.
A metaphor doesn't have to be a perfect match for what it's describing but the broad content and emotional tone should be similar and here I think it's hard to justify that this is the case.
