Step-by-step explanation:
According to the first constitutional amendment to the "Bill of Rights", an individual have the right to destroy or burn the American flag in a rally or in a protest against the government. The State considering a bill to ban the people from flag desecration would possibly be violating the people freedom of speech and freedom of action under the first amendment.
But in contrast, Citizens Flag Alliance publishing an article on their website favoring the proposed policy may be considered that they may find the destruction of the American flag to be unpatriotic or not in the favor of the nation.
They support this idea because consider the flag a national symbol of importance. So they support the government's proposal to ban people from flag destruction and try to influence the public in support of them. They may also carry out a mass rally in support of the bill so as to influence the Congressmen.
