Unfortunately age and gender does not mean anything to these people when it comes to their violence. Female suicide bombers are just as deadly as males. And CNN has a chilling link up to a video of ISIS training the very young on how to kill. Particularly disturbing is a young boy, not much bigger than a toddler that is being encouraged to cut the head off of a teddy bear with one of those big ugly knives.(note: I have not read past this post yet as it is hard for me to go back and quote under the new system; my apologies if I am repeating something someone else has already said)
So many recent terrorist attacks have had women and/or children (as young as 12 or so) as suicide bomber that I am not so sure that makes you any safer. Besides, I really do not see how it is right to deny anyone safe haven based on gender or really even age. As a mother I would be equally desperate to get my teen son as my teen daughter out of Nigeria or Syria or any other highly dangerous area.
