A lack of resonance doesn't prevent some concepts from being universal.
You're taking it too far by saying that no concepts are universally applicable to human beings.
If I made a post saying "We need to eat to live a healthy life", would that not be a universal truth? If it doesn't resonate with some people (e.g. some quibble: "We can puree our food and drink it" or "intravenous injection works for me", and ignore the serious disadvantages of both choices) is the scientific truth of "we need to eat to live a healthy life" not true?
Relativism to an extreme degree is next to nihilism.
