Absolutely, if Target wants to survive catering to 3% of the population, let 'em try.
I can count the times I've been in Targets. Now knowing they are seemingly in favor of, and supported by, "alien life forms", and my being the devout homophobe I am, I certainly won't be adding to that count.
I do understand they are not owned by any foreign company and have gotten some bad press from other things unrelated to the Salvation Army policy.
