Corporations do not respond to people. They respond to customers. They don't change their behaviour based on opinion. They change their behaviour based on financials.
As a Christian we each have a responsibility to be good stewards of what God has given us.
We vote every time we spend money. We are voting for the package, not just the specific item. The package is the product, the company and its sponsors.
Christians have been voting with their finances for bad packages for years. What we see in corporate America is a reflection of our financial voting. It's time for us to be more responsible.
