As for worries from some about the lesbian suggestion, get with the programme. If middle eastern countries don't like modern democratic attitudes, not ruled by dictatorial (male dominated) superstitions, they can quite easily shut themselves off from the modern world. Nobody forces such people to fly to the UK or USA, so it can't be all bad.
Besides from a commercial point of view, it's a pretty smart move chasing the pink pound. BA sponsored London pride this year, United and American have been doing the same for many years. They know where the money is. Ask any major advertising agency, and they'll tell you the same.
Islamists can always choose to use a suitably islamic airline. It's called freedom of choice.
