Unfortunately, not all of them are owned by the muzzies. The vast majority may be owned by Hindus and Sikhs (who have no love lost for muslims).
The best way to handle these barbarians to to draw up lists of muslim-owned stores and then appeal for a boycott. One clue to find out if a store is muslim or not - look for Arabic verses (the kind that look like worms) near the cash register or behind the counter.
Around Boston, they've been buying convenience stores and gas stations, even strip malls, but posting no verses.
That is exactly I do when visiting the "Stop & Rob" corner stores. We have two within five miles of our home and their business has dropped considerably since 9/11. Another local "Stop & Rob" went out of business some time ago and the building is still vacant.
