I haven't discredited anyone, that's just my opinion. I'd like to think I've read enough that I can chat confidently at parties, that's all. I think your opinion is fine too, and you have lots of friends at the parties I go to which is always a nice thing.
There is not anything sacred about "scientific consensus". There's always new hypotheses to test coming from outliers in any scientific field, always unexplained measurements to explore. Whenever I hear the term "settled science", I flip my wig. There's simply no such thing. My experiences with researchers at university is there is usually a pet theory chased by the lead researcher and you better toe the line or you get no grant funds. If most researchers are on the anthropomorphic global warming band-wagon then that's where everyone's head is at.
Yeah, well, the ugly vitriol flows both ways, I can attest. What you observe may be people who are grumpy being called idiots all the time and they're just lashing out, and probably just as many intellectually lazy people who like to troll. I wouldn't normally say anything in a forum that counters the popular viewpoint because I don't care enough to take insults, but people are mostly civil here at HN, thank goodness.
