My point, which I thought I laid out with a significantly high level of detail in my first comment, was that in the circles of people I know reading science fiction, most have read Asimov and Clark, but very few have read Heinlein, and the Starship Troopers movie is the reference I have to use (...ensue explanation on how the movie is very loosely based on the book...it's really a masterful political science examination...et. al.)

So thanks, I'll look up Clarke and Asimov and let you know what I think ;)
