FunkyDerek, if you don't see yourself as talking in circles to avoid the point, I hope others do.
You chose, "characteristic of or belonging to reality as perceived rather than as independent of mind," as an antonym of objective. I agree.
Love belongs to reality as perceived, that is to "subjective reality." It is therefore subjective, because that is what subjective means. There must be such a thing as subjective reality if your definition of "subjective" includes "reality as perceived." Love cannot be perceived independent of mind.
Some physical manifestations we associate to the emotion can be perceived independent of the mind but love, itself, cannot. These physical reactions are not love, they are the physical effects associated with love. These effects have names and are objective things, but they are not love. Love is subjective, it is a subjective experience and it cannot be defined apart from defining an experience as perceived.
I doubt you will agree. And that is okay with me, you don't have to.
