The American flag never dips to any other flag.
The American flag is always flown above all other flags. This includes the Don’t Tread on me flag for the TEA Party person in Grant County Kentucky. Are you that stupid???
When the American flag gets so bad that it is a disgrace to fly, take it down and dispose of it properly. The preferred method is burning.(yes that is correct) But when you burn the flag it is not while it is flying as the protesters do. If you unsure or uncomfortable, drop it off at your local VFW, American Legion or other location of that type. They will take care of it for you.
