In fact they do care about their wives and children. When a Jihadist dies in the name of Allah and takes infidels with him, his wife and children are taken care of forever by the local mosque.
That is a why Donald Trump stated we need to take out their wives and children, because if they know their wives and children will be killed they won’t do this anymore.
I dunno, they have been known to strap explosives to their wives and children. And, Muslims treat their goats better than they treat their women.
