Whenever I see someone corrects another person on their use of "literally", it often seems to me like the corrector did not realize the sentence was supposed to be a hyperbole, and in fact depends on the correct usage of the word "literally" (to mean "actually") in order to be a hyperbole. For example:
"It is so amazing it will literally make your head explode".
Sure, nobody's head is going to "literally" explode from the sheer awesomeness of whatever "it" is, but isn't that exactly the point? If heads do not explode from something being awesome, then something would have to be extremely awesome in order to actually explode someone's head. This sentence basically says: "The intensity of how amazing this thing is is so great, that your head will actually explode from it."
This seems semantically correct to me, but people seem to criticize this use of "literally", as if it actually isn't semantically correct. Why is that?
