A site called "Queer Beacon" offers a replay of the latest TV spot for the Dodge Caliber, which QB thinks is homophobic. While it does play off stereotypes, I can't say that it struck me as offensive. Actually, I thought it was somewhat amusing, and I'm fairly thin-skinned. But to each his own.
Some people also take offense at the Nabisco snack fairy commericals.
I remember some years ago reading a complaint charging that a
commercial for frozen dinners used the anti-gay voiceover tag line,
"They're not for queers." Turns out the ad actually said, "They're
not for quitters."
