~~I think you have it backwards, perhaps. Prescriptive is like when a doctor tells you what drugs to take via a prescription. That's the old man one. (Although I think it's quite often younger people who have recently had the idea of correct and incorrect useages of languages drilled into them!)~~ Oh, either you edited your post, or I'm crazy. :)

Also, while too much prescriptivism is certainly obnoxious, not enough has its own problems. Language needs a certain amount of conformity to ensure were actually having a conversation about what we both think we're having a conversation about.

Stop promoting bad English. English has rules for a reason, you can't just speak or write however you like, else we wouldn't get graded in English class, now would we?

Language can evolve all at wants, but Americans are still wrong whenever they say it.

Language has to evolve into something, the Americans seem to be trying to make language evolve away from coherence. You're probably the type that says using the word literally to mean figuratively is acceptable as well.

Languages evolve.

Funny how this canard is always directed towards the literate. It's only ever allowed to evolve one way, usually with some vaguely political bias towards the youth/against anyone over the age of 25, or as some kind of act of pandering to the lower classes or some minority group (willfully ignoring that the spread is in large part attributable to multi-billion dollar media organisations, and far from organic).

American English perhaps, "on accident" sounds absolutely absurd to most Brits.

Are you someone who thinks it doesn't matter if someone mixes up they're / their / there etc? These things do matter because if you don't use them correctly people are more likely to misunderstand you.

All of my English teachers were "old" women by the way, nice attempt there to shoehorn in some baddies. Nothing worse than old men, am I right?

Unless I’m reading this wrong, I think you’ve got those two linguistic approaches reversed.
