I believe it was Noam Chomsky who said that "everyone speaks their own language perfectly." By that he meant, of course, that the speaker knows exactly what he meant to convey. But will the hearer understand it in the same way? That is the reason for grammatical rules, to enhance understanding.
Logically, therefore, anything which inhibits clear communications should be resisted, but that which enhances it should be encouraged. The rest of the arguments are just language arrogance, one of the more common, garden-variety human traits. :)
