That's because gays were legitimately persecuted. Nobody has ever been arrested or murdered for being fat. Fats are retarded losers who cause their own issues and think a social movement will help more than actual movement. The thing is, fats will always hate their bodies because it isn't natural to be morbidly obese... while homophobic people argue that being gay isn't natural, there's nothing about being gay that inherently makes you miserable the way being 300 lbs with condishuns does. Old time gays who were trapped in straight relationships out of social pressure were miserable because the thing that would have solved their issues was illegal. The thing that solves fats' issues is neither illegal nor frowned upon, but it requires a modicum of effort.
