The point of the "questioning everything" bit is that if you question, say, plate tectonics, or the germ theory of disease, or universal gravity, you're pretty much a kook, and not really a healthily skeptical individual. There are people who disagree with all of those, too, but that's certainly no reason to question the scientific consensus on them.
And if you haven't bothered to inform yourself of the issues, wouldn't it be more honest to say that you do not know enough to take any kind of stance?
To give an admittedly overly dramatic example, would you say you have some doubts about the holocaust, because you haven't seen any evidence of it (let's pretend you haven't, even if you have), and that there are both people who deny it and who believe in it?
