I am a mother. Your valid points mean little when the safety of my child is called into question.
You are allowed to be wary. You are allowed concern. You are not allowed to quite publicly discuss potential weapons of defense against someone who has made no threat against you and will not unless you give him reasons to. Even then, he would likely try to dissuade himself from doing so.
Sif is nice. She is the daughter I never had and the mother to my future grandchild. However, she is not on the defensive as I find myself with you.
