Furthermore, how DARE they compare being fat to homosexuality. Gay people have been the target of far more vitriol and hatred than any fatass could ever dream of. Being gay is (largely) biological, whereas being fat is more under a person's control. Not saying a person can't naturally be chubby, but there is NO EXCUSE for any human being to weigh over 450 pounds (I'm factoring in really tall people here, or people with large frames).
I'd really like some LGBT group to find this article and condemn it. That'd be an interesting mudsling.
