Wow, I'm surprised and pleased that they actually do this. Go AS! They really do take their chances and stand out from the rest. I am a Christian so I think it's wonderful. But do you know what? If they were handing out Jewish info or horoscopes or something... I wouldn't find it "horribly offensive" at all (would you? what's the difference?). I would just say, "okay, whatever", and leave it behind.
Look at it this way... If the worst thing that happens to you in a week, or even a day, is that you are 'subjected' to viewing a Jesus card on your flight I'd consider you a very fortunate person!
For pete's sake stop whining and enjoy life!
