From the Army website:
The MAA's charter specifies that we are a patriotic organization, therefore it is lawful and proper for our members and participants to wear the US flag.WEAR OF THE AMERICAN FLAG PATCH
- The US Code states "no part of the flag should ever be used as a costume or athletic uniform. However, a flag patch may be affixed to the uniform of military personnel, firemen, policemen, and members of patriotic organizations. The flag represents a living country and is itself considered a living thing. Therefore, the lapel flag pin being a replica should be worn on the left lapel near the heart."
The MAA traditionally wears the US flag will be worn reversed on the right shoulder. However, any wear of the flag as specified above is appropriate.-The US Code does not address the positioning of the flag patch. It is appropriate to wear an American flag patch on the left or right sleeve. When worn on the left sleeve, the union would appear towards the front and the stripes would run horizontally toward the back. When worn on the right sleeve, it is considered proper to reverse the design so that the union is at the observer’s right to suggest that the flag is flying in the breeze as the wearer moves forward.
- Since the law does not specifically address the positioning of the patch, a decision is left to the discretion of the organization prescribing the wear.
Minnesota statutes specifcally allow the respectful and proper wear of the US flag.As many states and cities have ordinances pertaining to the use of the flag, you may wish to contact the Attorney General of your state or the City Attorney’s office regarding this matter
"Can I wear the flag if I am not a veteran?"
Yes. As stated above, MAA members and people participating in MAA events may wear the flag.
"Is a 'subdued flag' okay?"
The US military has approved the "subdued" US Flag for wear, effectively sanctioning its design. A subdued flag should be treated with the same respect as a full-color flag.
"The First Amendment gives the the right to wear the flag any way I want, even if other people find it disrespectful."
Under the First Amendment, you have the right to do that. It goes both ways. Under the doctrine of Free Association, the MAA has the right to exclude you from its events for doing so.
