Singling out SUVs makes no sense.
SUVs use more oil than alternative transportation; the more oil you use, the more you support terrorism. SUV drivers aren't UNIQUELY 'guilty' but they are higher on the list. (And would you really agree with an ad that said, "Unless you ride a bike, you're morally complicit in terrorism"?)
Exactly. It is not equivalent to the drug ads which do not single out any specific subset of drug or user in the way this ad does.
I can't believe, though, you actually take this seriously.
