Grammatical consistency is something that is entirely irrelevant, and only exists because people believe in it's importance.[/quote]

Language itself only exists because people believe it's important. The English language isn't a product of nature, so obviously its rules aren't either. Also, this is an appeal to nature fallacy.

Language's constant state of flux is not a reason to defy the structural rules governing language, but rather to reinforce them in order to sustain intelligibility in spite of the change. What is considered acceptable occasionally changes; that does not for any reason make it wise to abandon all rules determining what is or is not acceptable. Words are spelled a certain way. Words can only be put together in a certain way. Spelling a word incorrectly or organizing a sentence incorrectly introduces ambiguity, which is antithetical to the entire purpose of languages.
