The word you're looking for is empirical. Your example theories are empirical, but not scientific. A theory is only scientific if it's formulation followed the scientific method.
It might be better to look at the use of the word 'theory' - Aristotelian physics counts more as a hypothesis, surely?

Evolution is not just another theory that can be easily discarded. That is, frankly, a staggering misrepresentation of evolution's impact, to simply call it a "neat theory". In fact, I fail to think of a single idea in the era of modern scientific enlightenment that, having irrevocably defined an entire field and withstood over 150 years of scrutiny, is completely thrown away. It would mean that scientists have failed to faithfully interpret a wealth of fossil data, rich molecular evidence, millions of years of our planet's history, and many experimental results. It would be such a huge mistake that it would make us question the veracity of scientific thought. Because with this much information, there is no reason why scientists should get it wrong.
No theory that's had a lot of effort invested in it and survived a whole load of testing through the scientific method can be 'easily discarded'. They
can, however, turn out to be incomplete, accurate only in a limited way, and we still have to accept the possibility that they
are invalid, and just happen to map in some circumstances to reality. Some people take the view that all models that make the same predictions are equivalent and equally good; I don't agree with this.
This may be a fairly fine point of principle - I'm just saying that while I agree with you entirely that where there
is a theory that neatly and elegantly explains the observed facts, makes predictions that are upheld, and is supported by the vast majority of the scientific world (however you define that) you should believe it to be right, you
still don't get to say that anyone who questions it must be insane by virtue of the fact that they're questioning it. If you want to point out the insanity
of their criticism, then by all means do that. But taking a position of "I am right, and those who disagree are insane" as a blanket default is dangerous, and
leads to the acceptance of theories that later turn out to be incomplete or debunked entirely.
Incidentally, you're mistaken if you think I consider 'neat theory' a dismissive phrase. Science strives for neat theories - they just don't always stand up to scrutiny.

And if you think that I said that we should trust scientists on everything, then you've clearly misinterpreted.
What you said seemed to imply that where there is scientific consensus you should immediately bow to it because scientists are 'some of the smartest people on Earth'. If that's not what was meant, then that's the misunderstanding.

So why do we excuse evolution-deniers? Do we really think that their skepticism is a healthy kind of skepticism?
I think some of their skepticism
can be a healthy kind of skepticism. The problem lies not in keeping an open mind about something that should have an open mind kept about it (as should
everything in science). It lies in wanting to turn that open mind into
denial of the most well supported theory, and to supplant it with a model which is in no way scientific, and isn't held by its proponents to any of the same standards as they want to apply to evolution.
Skepticism is supposed to follow the evidence over dogma. At least some evolution deniers - probably the majority - do so by following dogma over the evidence, and that's the problem I have with their approach - they know what the 'right' answer is before they start, and the only use for evidence is dependent on whether it can be used to support that answer or attack opposing answers.
That's not an approach reserved entirely for the anti-scientific religious types, of course - it's used extensively in 'real' science by people wanting to defend their pet theories.
