Suppose there's this girl, and she is objectively sexually attractive. Also, her hair is red.
Next, suppose there are two dudes who see her. Dude 1 finds her especially attractive because he likes red hair, in addition finding her generally attractive, anyways, disregarding the hair color. Dude 2 doesn't find her interesting, despite her being objectively sexually attractive, because he doesn't like reds.
That's my best attempt. Very good question and interesting point you've brought up, H.
