I suspect that the author of the article you cite does not mean to suggest, as you seem to, that all of the other commandments have equal weight, or that any of them is equal to the to the Great Commandments.

I'm not even sure what point you are trying to make.  If you deny the primacy of love as the basis for the Christian life, then I would think that you are arguing from outside the Christian tradition.  Much of what you write seems to come from the Pharisaical tradition which Jesus so thoroughly repudiated.

But which is it that God desires:  Mercy or sacrifice?
