Of course you don't. A large portion of the people who watch launches, particularly those who go out of their way to watch launches, are quite knowledgeable about astronomy and science, so it's a bit like a party you weren't invited to.

Clearly you have no appreciation for astronomy, thus you see myself and other launch attendees as being equivalent to NASCAR attendees. You're so ignorant of it that you're also ignorant of how informed and knowledgeable other people actually are about it.
