I'm not bringing the fallacy of anything to the discussion. Merely pointing out where opinion is being presented as fact. You only get to decide what is or isn't science-fiction for you. Not for anyone else. Same goes for Azimov, Heinlein, and all the other big names you dropped. They don't (didn't) get to decide what people think SF is any more than you do. They just get/got to write it and present their version of it.

Study all you want ... there is no authority on what is or isn't "real" SF. Or what SF has "always been," or what SF need "always be." The label simply does not define, exclude, or encapsulate its content with any concrete, agreed-upon strictures. No matter how many people's personal definitions of it that you trot out as "proof."
