However, Neil deGrasse Tyson is my absolute least favorite scientist ever. I loathe and despise him with every atom of my being. He's a snob of the worst kind; got Pluto demoted;
He didn't "get Pluto demoted," he was just among the first to institutionalize it by choosing to update the Hayden Planetarium's equipment and not include it as a planet. The IAU decided, in light of the same evidence (Kuyiper Belt Objects) which Tyson referenced, that Pluto had more in common with these newly discovered objects than it did any planet, and so voted to reclassify it (or rather, to specifically define what a planet is, since no concrete definition had existed before then, which led to the strange situation of having anywhere between 9 and 15 planets in the Solar System, depending upon who was answering the question). Tyson had almost nothing to do with it.
Now it's standardized with actual definitions of things. That's what scientists
do: they categorize things in order to better understand them and how they relate to one another. Pluto belongs where it is now.
and he genuinely hates anything and absolutely everything that is not non-fiction. Not to mention the constant bile he spews about anything that is fiction. Especially of the science and fantasy kind.
Again, not true. He rails against fiction which claims to be scientifically accurate but is not. He has no issue with blatantly fantastical fiction, and has said so repeatedly.
Not sure if it can be taken as a positive that he is mentioned to be a frequent guest in those comedy shows (?).
I regard it as a positive. He has a sense of humor, but remains a scientist. His appearances are always about scientific things (he's friends with Jon Stewart, another New Yorker, and so comes on his show a lot because they're friends, but also to talk science to people, sometimes to answer some science question Stewart might have), even when being humorous. Rather like Nye's career sometimes: comedic, but still grounded in reality. The funny nerd, as it were.
I cannot stand Brian Cox. There is something in his style which really grates on me. Can't explain that.
I like him when he's not on a documentary. Like on QI or something, just talking to normal people about science junk. He does have a strange way when narrating a program which makes him difficult to sit and watch/listen to for an hour. Maybe it's something about reading scripts or whatever.
Also why do we need a scientific literate population for a democracy? Or is it just a proxy for well educated?
Yeah that's part of it. Another is part of the fight between the anti-scientific forces which resist technology and discovery. Creationists, natural medicine people, anti-vaccine, and the like. Maybe that's not as much of an issue in the UK, but it is in the United States.
Another is that if we are to have representatives from among us who are expected to make responsible decisions about things, including funding for projects (not just research, but everyday funding for programs in the country/state/city), then those representatives need to be literate in those kinds of subjects, and science is more important than ever, and will become more so. We aren't ruled by technocrats who decide these things independent of The People, so our population needs to know about the state of things and appreciate science and what it gives us if it is to continue to enable it to function.
