This is interesting. Can we come up with a punchy name for good uses of "reverse tabooing"?

One reason I particularly like the choice of the word "awesome," which is closely related to and maybe just a rephrasing of your first point, is that it is much less likely to trigger redirects to cached thoughts that sound deep. Moreover, since "awesome" is not itself a word that sounds deep, talking about morality using the language of awesomeness inoculates against the trying-to-sound-deep failure mode.
