I've wanted to respond to this fact you've brought up a few times. It sounds to me like you are either apologizing for basing your arguments on your emotions because you have more to fear with four sons. Either that or you are saying that I don't have enough emotion involved because I have no sons.
I think a good decision about whether or not to go to war should have NOTHING to do with how many children one has and what gender they are. If there are good arguments for going to war, then that's the right decision even if one has 10 sons, all in military service. If there is not a good reason to go to war, then having no possibility of the loss of loved ones is no virtue in arguing for war.
