Sometimes, municipalities still try to block protests because of politics/people they don't like participating, under the guise of some more neutral explanation (usually noise or safety). But judges generally take a dim view on such shenanigans, and they rarely pass scrutiny in the courtroom, since the government is then expected to explain the exact grounds for denial, and prove that it is relevant and narrowly tailored.
So I'm a little curious that if a protest is related to complaints about the government, will it get accepted (at most cases)?
