I wish this was more talked about, when people mention classic sci-fi. I’m an avid SF reader, particularly older stuff, and it could almost be a drinking game of how few pages it’ll take before you find an offensively outdated reference, no matter how great the book. But every time I’ve picked up a Heinlein, hoping to find more positive points in classic stuff, I’m left just…feeling ooky. An easy example being the lesser known Friday, with the “happy” part of the extremely unrealistic female protagonist’s journey: marrying one of her gang-rapists. I haven’t been able to make a dent in my stack of Heinlein’s since that nonsense. Too many other great and interesting authors that weren’t horrid shitbags.
