I'll counter with some questions, why is cannibalism considered immoral in your culture but there are some where it is not, and there are others were certain types of cannibalism or referential cannibalism is okay?
Please drive your thinking all the way back to the basis of the morals governing it and how it arose. Do you accept that basis as an axiom for everything in your life or do you pick and choose whatever society has told you are the correct ones? Is your system of morality really based on the original foundation for that morality, or based on social convention?
If you believe your moral system is "better" than just following social convention and has a deeper basis, perhaps some kind of religion. Do you follow all the tenants of that religion or do you pick and choose from those? Why and why not?
If you've rejected that moral basis for some things, why haven't you rejected it for all things?
If you are without a moral basis, what is the foundation you are using for your moral system? When you believe something is immoral, and somebody asks "why?" enough times, what is the answer?
Or have you arbitrarily just chosen some moral rules you think sound nice e.g. (don't kill each other), and rejected others which you think don't sound so nice e.g. (you must perform exactly these rituals, don't mix fabrics). Why have you done this? What is your guiding principle?
If we don't share the same basis for our moral systems, why should I follow your morals and you follow mine?
