Not to divert the discussion, but I think it's natural -- as in, according to the nature that God designed -- for women to be less ready to grab a sword/gun and defend some worthy cause.
Politics, war, home defense, fighting -- those things are in the man's domain, not the woman's. What part of raising kids, teaching them, being the heart of the home, etc. does fighting come in?
I don't have time to be write several paragraphs, so I'll have to assume you know the Catholic/natural role God meant for women. I'll give you a hint -- it's complementary, not identical.
In Christ,
Matthew
