So if, according to you, Star Trek isn't about Earth or Vulcan, then what does it matter which planet got destroyed? You make little sense.
Do I? Because if Earth was destroyed, we would no longer have any "Earth is in danger!" story lines that make up for almost half of the movies.
- Star Trek: The Motion Picture
V'Ger wants to destroy Earth.
- Star Trek IV: The Voyage Home
A probe is destroying Earth.
- Star Trek: First Contact
The Borg specifically target Earth to assimilate it.
- Star Trek Nemesis
Shinzon wants to destroy Earth.
- Star Trek 2009
Nero wants to destroy everything, but is stopped before he specifically destroys Earth.
For a planet that had no role to play in the original series (except for time travel), everyone seems to treat Earth like the center of the universe where if it goes, the whole existence of the Federation will go as well. I find that rather silly and counter-productive to a series who's focus has been on space exploration and unifying multiple races in the galaxy. You're not going to get a lot done if all we do is come back to the planet where we started. But now that we have no Vulcan, we have less alien worlds to explore and more predictable "Earth is in danger!" story lines that our brilliant writers have left future Star Trek writers with.
And I don't recall anyone being happy about Vulcan's destruction at the end of the movie.
Well they sure didn't seem bothered by it in the end. Of all the folks who I think would be most bothered by it would be Uhura. Her boyfriend just witnessed his his home world destroyed, his mother murdered and has now tasked himself to help the remaining Vulcans survive. I thought that if she was in any way that emotionally connected with him that she would want to lend her expertise to help out. But no. Instead she's on the bridge of the Enterprise with a big smile on her face gleefully calling Kirk Captain. And this was before Spock's surprise appearance.
I don't think Vulcan or the remaining Vulcans are going to be missed.
