Is it true that there is no absolute morality?

This is not quantum mechanics, which is something I can't even begin to make any educated assertions about and I doubt you can either. This is a plain logical negation argument, which you are blatantly violating. Do you understand the basis of logic?

I don't care too much which side of the subjective/objective argument you are going for (although I have my own opinion about that). Just at least pick one.

I drink hot chocolate.  I experience what the hot chocolate is like.  My brain is doing stuff, which is physical stuff, and the physical process can (to a degree) be observed-- there's brain activity happening.  So it's both subjective and objective.

Those are two separate things you are equating. Perceptions are just electrical impulses in your brain based on what your body and brain can detect. Your personal perception of the hot chocolate and the actual object of the hot chocolate are not the same thing. The color red as a property of an object is not affected in any way by a blind man's inability to see it
