Why Hume's views on art are biased

Hume's  idea although well thought out, seemed to be quite biased in the sense that it excluded many people who would be able to give a very well thought out criticism on what a good work of art is and what is not. The “distractions” he says that inhibit a persons ability to be a qualified judge are things that most people in this world deal with on a daily basis. For example the "distraction" of being young and in love. One's age has no way of interfering with how one perceives a piece of art as well as how one relates to a work of art. As well as being in love, the feelings you have towards another person can no way inhibit your ability to look at a work of art an appreciate it, or reject it completely. No one is able to succeed in being free of all distractions, there will always be something that will be in the back of their minds that may or may not affect their personal views on things. Therefore in some sense no one is really qualified to judge art based on his theory.
