Really? It seems to me to be Americans that are circumcised. But maybe that's just the er... models (snerk). I guess if it's a religious thing then all the American "models" must be Jewish! *(I'm guessing Jewish, I don't know anything about religions, sorry)

Makes no difference what the religion is, the point is, I'm not religious so I don't expect to see this kind of thing on a Poser figure; the figures should be neutral by default. 

Hopefully they'll rectify it and ensure they conform to default human male anatomy.
