Alex Bennett's theory is still a work in formation. My mentee Alexander Bird, who I called Steve McQueen in my piece to avoid confusion, tries to address relativism and Bennett's truth units in the latter's piece that I edited in the link to but did not discuss because while I had seen the draft a week earlier, it was not published till a few hours after mine. https://medium.com/philosophytoday/why-studying-theories-of-truth-is-so-important-58b22bd4fe57

Bennett responded to McQueen: "Thank you very much for talking about truth units, and for introducing it to unfamiliar readers. Your thoughts make me realize I've not dealt very directly with truth units as what might be a social norm for managing the balance of absolute vs relativistic truth. I'll work to address this soon. As I understand you correctly, the intent of such a norm is to find a healthy middle way between extreme open-mindedness (relativism) and extreme close-mindedness (dogma). Again, thank you!"

My post is a reaction to and designed to continue discussions, which is what your comment does, Henya, and I thank you.

My own take on relativism, though it may be a digression, is that morality is relative but ethics are absolute.
