I Don't Think That Americans Have the Right to Fly

Multiple Choice

I don't think that Americans have the right to fly other countries' flags, I really don't. If this isn't illegal, it should be. If they want to fly another flag, let them go to live in that country. It offends me very, very much. (From a newspaper call-in column)
