>So atomic mass is subjective? The table of elements is subjective?

So you can't compare SOCIAL ENGINEERING to something that is subjective -- you want to compare it to atomic mass?

There's no point discussing things with a person who breaks so many rules of logic.

>It’s sounds like it’s all about people and their subjective reality.

Yes. Like your reality where you think Atomic mass being a stable number everyone can determine ALSO covers whether they think their outfit makes them look fat.

There is "objective reality" -- well, as far as you know, so far, with humanity's limited perception of the Universe. But, people interpret everything. Some people do not eat eggs because they are Vegan. 3 Eggs is objective fact. The "Truth" that what you gave me is a good thing, is an interpretation. And you assume how other people think based on your experience.

Reality and truth are subjective as hell. Facts are data points and can be accurate, but WHICH FACTS are we considering? "FACT; there are three eggs -- I win!" Okay, what were the rules? "That's a secret."
