And how would the Equestrians know of it beforehand?
It'd be, again, cheating to conduct perfect negotiations with a race and an entirely different culture before anyone else had ever talked to them.

This is more realistic, but I'm afraid this is about as realistic as it gets. It's sad, I think, because you can't really have all the cultural tension and all that. When one race tries to merge with another race, it wouldn't be seamless, like the Equis Pact or the AIF. There would be so much tension, from language making it hard to communicate, to different celebrations and even different ways to greet people. What may be a greeting to one race may mean nothing to another, or may mean the greatest insult.

And instead of the Equestrian saying, "We're sorry, but we're unfamiliar of your ways, could we have a demonstration of proper verbal interaction?", I just get an OOC saying "You misinterpreted my post's meaning!"

What is the fun of being an [i]entirely different race with entirely different meanings and cultures[/i] if it's as if they all have the same basic culture base. We should just all be different human nations, with all the cultural separation and tension there is.
