Shitty soup

If I reject your moral imperatives against, I don't need to find moral imperatives for, I just need to be happy that it's ethically neutral.....

No. Once a moral imperative is established, an opposing moral imperative is required to 'reject' it. This could result in either a dilemma or an outcome in which either imperative would prevail (in your moral judgement, by the way--we're not talking about Platonic forms of ideal moral facts; moral agents are self-governing/morally autonomous). Neither dilemmas nor the other outcome would be morally neutral.

like your standing up/sitting down example, which needs context Ollie, in order to be convincing ;^)

Actually, no--I'm only giving the example in this reduced form. Supplying more context would create a more specific example, which would quite conceivably have a different moral evaluation. (I do take note of the smiley, of course.)
