Bad father?

I've run a personal campaign against McDonald's for as long as I've had kids. As a result, they behave pretty much as the sign on the left suggests. Does this make me a bad father, denying my kids the chance to enjoy junk food?

(You can make your own sign courtesy of a website campaigning against McDonald's giving away model Hummers as part of McDonald's "long-standing global commitment to environmental protection and leadership.")
