It's been said that English is a language that is easy to speak/write poorly, but hard to speak/write well. It's a mutt of a language, combining many disparate and conflicting backgrounds. The pronunciation is always going to be confusing because the parent languages have absolutely loony pronunciation. Yeah, I'm looking at you, French, with your weird ass dropping of letters. Plus it's undergone a great deal of evolution. Anyone who turns their nose up at deviation from "proper English" ignores that their own use of English is a deviation from just decades prior.
