Same Sex Marriage Black List

While driving home from the office today, I was listening to the CBS evening news and heard a piece about how the ban on gay marriage in California that recently passed is affecting local businesses. It seems that if you contributed to the campaign to ban gay marriage, this fact is part of the public record, so proponents of gay marriage have created a black list encouraging people to black list those businesses that contributed to the campaign to ban gay marriage. Is this right? Should your political and social views be part of the public record and should people be able to publish those views and encourage people to hurt these people's businesses? I would love to hear people's thoughts on this subject. Please post your opinion here.
