Friday Discussions: Should Christians Boycott?

The Friday discussions have been fun. Thanks for participating. I hope you will join the dialogue. Remember, I like discussion, so don’t be bashful.
Today I want to know your thoughts on the subject of boycotting something you don’t support or believe in as a Christian. Recently I saw a group boycotting a business in another city. I won’t share the companies name, but apparently this company supports activities the Christians didn’t support. It made me curious:
Should Christians boycott products or companies because of things they are doing that may be seen as “unchristian”? Do boycotts work?
Do you think a boycott helps or hurts the cause of Christ?
What would cause you to boycott a company or product?
Would you ever publicly boycott a church if they failed to do as you think they should?
What boycotts come to your mind when you think about this issue?
Share your opinion on this issue.
