I do have to admit Dagless, it's a pretty difficult arguement to refute that you're making. I mean if the company capitulated under the pressure of the Muslim community to introduce a Halal only menu, then perhaps the aggrieved parties would have had a pretty conceivable arguement, but this the company did wilfully and of their own volition, and like you said, it was undisputably within the parameters of the law, so they cannot accuse the company of discrimination, i agree.
Not really. Even if some Christians did think of this, we worship the same God as Muslims, so that point is redundant. If it was sacrifices with pagan gods in mind, I might have a different view...
