Most Sci-Fi is Hellagay

There's only a handful of good sci-fi books the rest is escapist fantasy that would only appeal to the most sheltered sort of nerd who takes no solace in reality today.

I like Starship Troopers, Brave New World and Slaughterhouse Five.  All those books have strong sci-fi elements but are firmly grounded in reality.  If your the type of person that enjoys "Star Trek: Return from the Gamma Quadrant" then you are a fucking waste of flesh.

Are there any other sci-fi books out there that you think I might enjoy?

But NOT Hubbard - that guy invented a fucking religion simply because he wanted to fucking make money. Scientology. He then proceeded to make it so that worshipping cost thousands of dollars every time, and that followers were nagged heavily as heck.
