I believe this is a common sense way for Christians to cast a "vote" in the culture war that clearly exists in America today. I am free to spend my money where I want to, and so are you. Why should I spend money at a store that is allowing men to go into women's restrooms and changing areas?!
Here is some info from the American Family Association (AFA):
The Target boycott, launched in April 2016, is causing a significant drop in foot traffic to the store. Effects of the boycott are clear in Target’s financial report released February 28. The report indicated a dramatic drop in Target’s sales and earningsduring October, November, and December. This bad news for Target resulted in the company’s stock value dropping 13 percenton the day of the report.
Target, however, remains willfully blind to the link between the boycott and financial loss, but this blindness should not persist. Investors will hardly allow a politically correct bathroom policy based on a minority opinion to sink Target’s profits further. Target investors must be aware that a strong majority of Americans believe the use of restrooms and dressing rooms should be linked to a person's biological sex We must keep the pressure on Target.
Visit there site to join the boycott. Personally I hold nothing against Target, but I'm not shopping there until they change this policy. Perhaps they will one day like to have over 1.5 million shoppers back in their stores!
