You are right, she obviously had nothing to do with those events. She is a mother distressed by a very ugly incident. She is like any other mother afraid for the safety of her children. The fact that she is Muslim is immaterial. In order to get over her fears, she should, perhaps talk to other mothers. I would suggest she contact mothers of Canadian soldiers who served in Afghanistan and who are currently serving in Syria. Perhaps the mother of the young soldier killed while guarding the National Cenotaph. Perhaps other Muslim mothers who lost children in the lands fro which she came. Mothering is not for snowflakes - Canada is not free of danger and her situation is, unfortunately, far from unique.
