Do your homework. Make sure the stores where you shop are not Muslim-owned or the restaurants where you dine don't employ MUSLIMS in the kitchen preparing the food you eat or washing the dishes or sweeping the floors or clearing your tables or serving you. Or designing the clothes you wear. Or the cars you drive. Otherwise you are not PURE. You are faking it. You are a phony.
