I'm not disputing that they are being used, I'm just disputing it's not religious.

You could ask why our leaders don't put themselves on the front line as well in that case. Any army requires leaders and soldiers, and religious ones are no different.

I would introduce a law that requires the children of any mp (of the right age) to be drafted into the forces when the country goes to war. (that's a separate point, but it was on my mind).
