The question here is whether he is justified in his caution. But he knows it's his opinion, and not a universal truth.

This would be consistent with Gandalf's opinions about other things--the palantíri come to mind. Tolkien is quite clear in the essay on them in Unfinished Tales that Denethor, as Steward, had full right to use the Anor-stone, and that Aragorn had the same to use the Orthanc-stone; nonetheless, Gandalf sees it as highly dangerous to do so, and even cautions Aragorn (his closest collaborator in many respects, and possibly the Man he trusts most) about doing so.

This is, I would say, Gandalf's normal approach, and it makes him quite different from Saruman. Whereas Gandalf approaches such things with as little pride as possible, Saruman basically says "oooh, something I can use--let me test it to the fullness of its abilities, without regard for the possible consequences."

All of which is to say: I agree with lalwendë that a caution from Gandalf about the dangers of a "trifle" suggest that something like the Lesser Rings weren't so much evil as potentially dangerous--like, for example, a teenager with a motorcycle.
