Growers Market Controversy

At the Growers Market here in Grants Pass there has been an ongoing controversy over Christians who show up with their signs protesting abortion, and some of the merchants who complain that their noise level is making it difficult to communicate and conduct business. There are also people showing up with loud radios and drums trying to override the peachers adding to the noise. From my perspective this is a first amendment issue that should not be restricted, but I do understand the merchants who say it makes conducting business difficult.
