I know this will not convince you; however, here is the Wikipedia
definition of "astronaut."
http://en.wikipedia.org/wiki/Astronaut
Dictionary.com defines it as:
http://dictionary.reference.com/browse/astronaut
You don't have to be a pilot to meet the "travel in space" definition.

OK. So anybody who has a bazillion dollars and can buy his/her way into
space is an astronaut? So I could win the lottery and buy my way to the ISS
and that would make me an astronaut???

What a disgrace to those brave men who risked, and lost, their lives to
advance the state of the art.

Gus Grissom, best stick of the bunch, once dead sticked an F-86 into WXOF
(know what that means...?) would be, I think, absolutely paralyzed by your
and the modern media's definition of what an "astronaut" is.
