Was this business prohibited from flying a flag? Are the protestors saying he was not allowed to fly a flag at all or that he wasn't allowed to fly the biggest flag he wanted to fly?

If the controversy was that he couldn't fly the biggest flag he wanted, then why not focus on changing the law to allow flying the bigger flag? If the officials were just enforcing current law, then whether or not they agreed with the law is not the issue.

Just for the sake of argument, does a bigger flag mean someone cares more about this Country?
