You clearly have strong opinions about this. You bet I do, James. You pick the aberrant behavior and SF has supported it. A lot of people would claim that it's this kind of openness that has kept sci-fi vital after so many years. Over the last thirty years, science fiction has been nothing but a platform for the destruction of the values the Western World has held dear for so long.
People talk about how science fiction is about hope, how it offers up a vision of a better world.
Well, I don't know about you, but I don't consider a world in which the government forces me to pay taxes to assist free-loading aliens to be a better world. Look, in my own game, Visions , I've tried to present a fully realized world with as much depth and diversity as our own. Because that's not what people would want for themselves. Neither was universal suffrage or integration or even daylight savings time. Yet few people would argue against the goodness of these things now.
