I don't see any particular reason to eschew common or obvious references to history or literature because they are easy or common. If that is honestly something that bothered us, we would be complaining at the shear number of western authors who have been falling back on biblical allusion, or greek mythology for centuries (both in fiction and otherwise). It is easy to reference The Tower of Babel, or the story of Icarus, but we don't complain when people do.
(I know, I know, being an easy comparison isn't the real reason we complain about references to Hitler. I don't find the real reasons to be compelling either.)
