I must confess to being of 2 minds on this issue. Yes, I am in favor of a positive campaign for gay marriage and gay civil rights. However, though I may be skeptical of the effectiveness of boycotts, I'm not willing to spend my money with a business that believes that I'm not, and shouldn't be, a full and equal citizen.
The reason those big rallies on Saturday were so necessary is because politicians and businesses pay attention to numbers, and numbers mean power. Why should we be reluctant to use that power?
The boycotts of businesses during the Civil Rights campaigns of the late 50s early 60s hurt the economies of many towns in the South causing foreclosures and layoffs. I'm sure Dr. King did not get much good will from the unemployed workers or bankrupt owners of many businesses. But, Dr. King understood, as Gandhi understood when his boycotts hurt British industry, that nonviolent struggle is still struggle, it is using your power.
Indeed, payback is a bitch.
