I can't tell if you're being serious or facetious.
A given moral rule doesn't change because it's held by you versus someone else. Just like it makes no sense to refuse to answer the question of whether a fruit is an apple because it is in my hand instead of yours.
In other words, by having a moral rule yourself, you implicitly have a moral metarule: a rule about how to choose your moral rules.
Your refusal to answer the question doesn't make sense.
