^ Of course not. Star Trek is the perfect example of soft science fiction that clearly falls within the category of science fiction, but most media doesn't fit so neatly in one of the two categories. Sure, you can always use the Science Fantasy label, but when that covers the majority of science fiction and fantasy it's just getting silly.
Fair point. I may have been a bit snappy...we got in a furball over the idea that anything that wasn't "hard" sci-fi was full-on fantasy not too long ago over here, and I'm still a bit touchy.
Didn't mean to take it out on you.
