There's not really much to object to in that article, though it is interesting that you have such strng feelings about the organization yet apparently haven't read their primary documents.
I don't really intend to read them, to be quite honest. I'm usually quite dismissive of most pressure groups, and this one is no exception.
The militarization of space is of course inevtibale, in fact it has already begun. Can anyone doubt that the US military for 30 years has relied on military platforms in outer space (communications networks, reconaissance satellites, ballistic missiles)? It doesn't seem rational to me to pretend that the militarization of space is a future event that should be avoided, when its obviously a current and long standing condition that should be exploited.
Perhaps I've been watching too many sci-fi movies, but I really hope that the human race never sees the day when a Death Star (or something similar) becomes a reality. A major argument against space exploration in general is that we still have too many concerns down here on Earth. Wars and other diplomatic disagreements are a good example of this. If anybody wants to start a war anywhere at any time, for the sake of humanity just keep it on your own turf.
