The tone of your post screams "I'm the type of Brit who gets angry about linguistics."

I'm quite well aware of many of the differences in spelling and pronunciation. And I am very familiar with the OED. That doesn't mean your spelling is the right one, nor mine.

Also, just because you're supposedly exposed to more--clearly it doesn't make you folks any more tolerant.

(Just to be clear, I'm not calling Americans utter twats. I'm saying that they're less likely to be aware of the differences and are therefore more likely to assume mistakes where there aren't any.)

No offense, English doesn't belong to only you anymore. I have no issues with British English. But, I've heard plenty of Brits go on tangents about American English for example.

Also, ya'll still have colonies?

My tone screams of mild academic interest. And I'm definitely not a Brit.We agree, then. Excellent Obviously. And if you're aware of the differences in writing etc and still argue that the other guy is wrong, then that makes you an utter ****. Which is why, in my experience, it's the British-English speaking person that is often arguing that so-and-so is actually correct while his/her American counterpart is disagreeing.None taken! I don't claim English, I just profit from it! And one can be upset about something without denying its validity. Politics, for example. Oh wait...Bermuda, the Falkland Islands, Gibralter, the Virgin Islands, and the Sandwich Islands all still retain their colonial status, I think. So I guess they still kinda do, yeah.
