Anyway, I find the characterisation in the series quite colour-blind when it comes to depicting characters from a multitude of origins, and I think Gatou and the illustrator (don't know whether to use Douji, Shiki or ShikiDouji) did a remarkable job in handling religious backgrounds.
As evidenced from the novels:
Lt. Grouseaux, a devout Muslim, doesn't drink alcohol. (Check.) He is also a positive role model as far as is evidenced from the novel - tolerant of the beliefs of others (McAllen), fair, even to people who don't like him and vice versa (Kurz), understands situations very well, and kicks the ass of anything not equipped with a fully-functioning Lambda Driver (and then some). And, of course, he's one of the good guys. I was a little disappointed, then, when TSR decided to remove all reference of his religion from the adaptation, because his actions in the bar didn't make sense then.
Also, Sousuke's thoughts on Christmas and Ramadan in DVMC seem on target. And with respect to Christianity, the ODBD novel also pulled off Tessa's benediction quite nicely. Sounds about right.

I have no idea what the novels say with reference to Shinto, though, but it would be pretty embarassing if he didn't get them correct.

As mentioned, Mithril is, as expected, a UN of mercenaries, and if any race in particular is missing, blame it on lack of exposure rather than any actual discrimination intended. And considering how FMP is set in a world where the Cold War never really ended (not that it's a big issue anymore), it was definitely a nice touch to put both a Russian and a Briton that high up on the TDD's command chain.
Race is rarely an issue, except for wondering about nationalities (Grouseaux again) and where cultural factors would come into play (Mao in Hongkong), and characters are depicted without devolving into any particular stereotypes...
...except for Grouseaux's fighting style. Is it too much to ask that a dark-skinned character (who was described as actually being a tone closer to Arabian) should have a fighting style that doesn't resemble breakdancing?

So does anyone have any thoughts on this matter? I might get to the issue on culture later...
