When is it a appropriate to burn the flag?

When you want to see how fiercely the nation represented by the flag you are burning defends your right to speak freely. Just be prepared to face the people who will freely share with you their disgust at your actions.

ANOTHER ANSWER:

The way I understand it. If a flag touches the ground, it is considered to be soiled and needs to be destroyed. If a flag has holes in it, is tattered or soiled, it also needs to discarded. Since throwing a flag in the trash is considered to be disrespectful, it should be destroyed by fire. Look for an American Legion Post in your area. They will have a flag collection box or give it to a worker there. Ask them what day and time the ceremony will be. Go see it. It is an honor to see a ceremony where people treat the flag with so much honor, that even though they are burning the flag, each person there once served that same flag at one time in their life and still do.
