I have already explained why the way offside is determined by VAR is not “factual”.
Two people, assessing the same incident, using the current system, with it’s many limitations, can arrive at two different determinations (offside/onside).
That, by it’s very nature, means it is a subjective decision, regardless of your stance on whether VAR is or is not used to manipulate match outcomes.
Again, the “fact” of whether the player was offside or onside exists. But that is unfortunately independent of the subjective determination made by VAR.
This is not a matter of opinion; it is—ironically—a fact, so I am not sure why people are still trying to claim that VAR offside determinations are factual.
