Nah, I'm betting the marketing people asked him to say stuff like that as much as possible. It effectively drove home the message that this wasn't going to be Trek made for those Dirty Trekker Nerds.
Doubtful. However bad press is still press and can result in more ticket sales, but usually by saying something more controversial.
I say embrace your trekker nerdiness...especially since a good part of the intelligensia embraced Star Trek.
