This may be related to the objectification threads, but I want to frame the question a little differently.
It seems to me that if a man who was dating a woman suddenly "came to terms" with the fact that he had a strong preference for women with big boobs, and left his girlfriend to seek out big-boobed women, he would be rightly condemned for being a shallow, narrow minded jerk who was thinking with an implement below the waist rather than with his head.
Why should coming to terms with a preference for BBW, and/or leaving a thinner women to seek out a fatter woman more to one's preference, be treated any differently?
