Here's another thought, which should be a general rule, about this topic and others. It's going to sound condescending, but there's nothing I can do about that.

Study and research are valuable things. So is science. If you haven't read up on a subject, you shouldn't expect your opinion to be better than someone else's who has studied it and given it deep thought for years. I'm not saying my opinion is going to be better than yours -- I'm saying it takes an arrogance to say "sure, you've read about this for ages and I haven't ever studied the subject, but you're just missing what's totally obvious!" By saying that, you are wantonly denigrating a lot of very smart people's hard work and study and writings. Wouldn't they have seen it themselves if it were as simply obvious as "the nature you can see in front of your eyes"? And anyway, what makes you so confident that your offhand opinion is stronger than the measured, thought-out opinions of those who have studied the content deeply for a long time?
