Starbucks

Read this link in the title before you read any further.

Starbucks has a program where they print quotes on their cups that express opinions from many different people. The question I have for people is this. Starbucks has given money to gay rights organizations and many other organizations such as Planned Parenthood. The question I have is...at what point should a Christian stop supporting these type of companies? Now I know that everyone loves Starbucks and it really does have great coffee. I am not a big fan of boycotting places but when I see these type of companies giving money to organizations that support abortion, that's a tough one. What are your thoughts?
