Does it matter? The fact that they're catering to those that choose to live the gay "lifestyle" in any country is sufficient to lose my business.
Well, the British sense of humor is pretty different than here. If a British audience would take that ad as sarcastic, and laugh that the mom turned into a deli man, and say “Ew!” when s/he continued to flirt with and kiss her husband after the transformation, then there’s probably no harm done. But most Americans would take the ad literally and think it was supposed to be an actual gay couple with kids, and this was being shown as an OK family model. I don’t know if the ad is just a joke in England, but I definitely would not want it shown in the US.
