I got a lot of that crap on CotI (repeatedly) from people who really hadn't the faintest idea even of how science worked, let alone anything astronomical. Nothing posted here (so far) is anywhere near that bad though.
The thing about Science Fiction is that it's arguably about taking what we know about science and the universe and extrapolating it forwards. I think when people try to separate the "science" from the "fiction" and push one more than the other then they're missing a really fundamental point of SF: that they're not two separate concepts that can be adjusted on sliding scales, but are instead a single concept called "science fiction" - i.e. "fiction about science".
And for all that people talk about how cat people and dog people and reactionless drives in Traveller are fantasy, are they really? The "cat people" aren't even cats, they're aliens that bear some similarities to terran cats - and if you accept the concept that there may well be advanced alien life out there, why couldn't it look a bit feline?
The "dog people" are genetic uplifts from terran stoc. Geneering is a very common concept in serious SF and has been for ages (Island of Doctor Moreau, anyone?) and frankly looking a lot less improbable in the not too distant future given the advances in genetic engineering over the past couple of decades.
The reactionless drives may seem fantastic today, but we do know that we don't understand gravity very well and certainly can't manipulate it - who's to say, someday in the future we might figure that out and learn how to bob along on gravity waves or something. So are those things really as unrealistic and fantastic as some people make them out to be? I don't think they are.
Even Jump Drive (or more precisely, FTL) isn't so impossible really - we may yet be able to figure out a way around the speed of light (be it by wormholes, portable pocket universes, or other means. There's already a load of theory on the subject), and I certainly don't think that Einsteinian physics and relativity is the be-all and end-all of our understanding of the universe. Maybe someday someone else will come up with something equally revolutionary, of which Einsteinian physics is but a subset (like Newtonian was to Einstein), that will reveal ways to circumvent the speed of light.
Really though, I don't want people to see science and realism as the enemy or antithesis of "fun SF gaming", because there's no reason for that at all. But you do have to have an open mind about it - in my experience, people who just aren't interested in it are very unlikely to change their minds about it.
