This seems to invoke the old "murderer/self defense" argument which is a false dichotomy. The logic seems to run something like "If you except all ethical propositions as equally valid then you must allow the person who wishes to kill you to do so because defending yourself would necessitate invalidating the ethical proposition that this person has the right to kill you." This fails, though, to take the logic to its fullest conclusion, that being "If all ethical propositions are equally valid then the proposition that I have the right to defend myself is equal in validity to the proposition that the murderer has the right to kill me."Brain said:Moral values are created subjectively but contested through multiple discourses of power. Claiming that your morality prohibits killing won't stop someone else from killing you if their morality allows it, or if they simply disregard their moral prohibition. Therefore, if you're going to accept that someone is going to kill you or someone else on the basis of their own moral/ethical values, why wouldn't you accept that you or anyone else has the right to a morality/ethic in which they push their values on other people? At least moral paternalism can be discussed, unlike killing (and intimidation by violence) which is what people generally exercise in protection of their right to cultural freedom.
The argument disingenuously purports to deconstruct relativism based on relativist logic when in fact it cuts in and uses objectivist logic for its final conclusion. It bases the conclusion on the principle that two mutually exclusive propositions may not be simultaneously valid but this principle only holds true if we are considering objective validity. Relativist logic states that the objective validity of any ethical proposition is exactly zero. If we consider the validity of any ethical proposition as subjective only the mutual exclusion principle does not apply and the dichotomy disappears.
