Before I get to the example, let me make a point about English usage. People say often use phrases like, "the moral principle x" or "this is the moral thing to do in this situation". By saying that they imply, at a minimum, the statements "the principle x, which
I wish everyone adhered to", and "this is what
I wish everyone would do in this situation", respectively. So far, there is no deep philosophical insight involved. It's just an observation about everyday usage of the adjective "moral".
The philosophical insight is that we can take the definition implied in common usage and use it as an empirical test. And that's what brings us to the example you ask for.
For instance, suppose I was to say, "the moral thing to do about waiting lines is to cut right in front". You disagree. Would you and I just be having a subjective difference in taste then? No. You would be right. And what's more, you could refute me as follows. First you'd ask, "
Why would you be cutting in line?" I'd answer: "to get ahead and save time." (That would make "getting ahead and saving time" my
maxim in Kantian terminology.) And now you could say, "But Thomas, if
everybody was to cut in line,
nobody would get ahead or save time. Your stated maxim self-destructs when everybody follows it. Therefore, cutting in front of other people in line
isn't the moral thing to do, at least not for this reason. You're wrong, Thomas". And indeed, your moral judgement would be objectively right, and mine would be objectively wrong.
Does that make the point clearer?
