In expressing opposition to the proposed casino in Prince George’s County, Margi Willis [“ ‘Vegas on the Potomac’? No thanks, ” letters, Dec. 24] wrote that she and her husband would never go near or support any of Maryland’s casinos. That is exactly the point. Ms. Willis is free not to patronize them, while others who have different tastes are free to visit them. That is what freedom is.
