> Having a distinct culture doesn't necessitate having a distinct language, but having an existing distinct culture in a specific language necessitates preserving the language for preserving it
I'm not saying other languages shouldn't be preserved. I'm saying there should be a standard language. I don't think that one precludes the other.

Maybe, but why would that be worse (or better for that matter)?

That's an interesting point, but on the other hand I'm still not convinced that this means that having a lot of distinct languages is "better". While on the other hand, there would be clear benefits to everyone speaking the same language or having at least one common language.

Isn't that what always happens with all culture as it evolves?

This is where I strongly disagree. I think that some things are tools for a specific purpose and should be standardized. Language is a tool to convey facts and ideas.
I recognize that culture should not be standardized, of course.
