Or the musician before you buy a record or attend a concert? Or the star before you see the movie? Or the author before you buy a book? Or the TV show host before you watch the program?
If you don't you are not PURE you're a phony. Hate has to be consistent not partial. Hate is not something you particularize to suit you. It is across the board and immutable. Hate is not the tree it is the entire forest.
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.
