A demonstrator carries a sign that features a logo expressing disagreement with a government policy. The demonstrator and sign is an example of what kind of protected speech?

The demonstrator and sign represent symbolic speech, which is a form of protected speech under the First Amendment. Symbolic speech involves actions or symbols that convey a particular message or viewpoint, rather than just spoken or written Words. In this case, the logo and the act of demonstration express dissent against government policy, thereby enjoying protection as a form of political expression.
