War Veteran told to Take Down US Army Flag

Under the California Constitution, courts consider whether use of a particular facility for speech activity would interfere with its primary use. If not, then it is available for public use. In other
words, the test is whether speech activity is fundamentally incompatible with normal activity.
Courts have made clear that mere “annoyance” or “inconvenience” are not enough to meet this
incompatibility threshold: “Annoyance and inconvenience…are a small price to pay for
preservation of our most cherished right.”

I say leave it up and take it to court. Just because there is some legal policy doesn't mean that its constitutionally legal.
