As far as I can remember, Ben & Jerry's did not include the fat acceptance movement. Why?

An initial thought is that they are already customers, or otherwise not in their targeted market. Cartman, with his Oppenheimer cereal bombs, is not high-class enough to have wholesome-ingredient luxury ice cream appeal to his consumer habits.

Are metropolitan middle class white liberals and otherwise people who want to give the image that they care for the welfare of others - just better and more obedient consumers - especially when the product is wrapped up in a “feel good” wholesome or socially responsible package? Is this a perpetual sort of trend in advertising and retail/corporate response for demand - “Buy this, feel better about yourself - You have more money and want to feel [even] better about yourself, buy this and feel better.”

Do people not care because why not just exploit people with a disposable income?
