What is the current state of the law in the context of advocacy for same-sex marriage?

The leeway afforded advocates is the greatest where the audience is the general public or is a voluntary rather than involuntary participant. See Madsen v. Women's Health Center, Inc., --- U.S. ----, ----, 114 S.Ct. 2516, 2527, 129 L.Ed.2d 593 (1994); Frisby v. Schultz, 487 U.S. 474, 484-85, 486, 108 S.Ct. 2495, 2502-03, 2503, 101 L.Ed.2d 420 (1988). The general public is a diffuse body that is not easily coerced by words or non-violent symbolic acts. Where more than fleeting exposure to the advocacy is avoidable, moreover, the chance of coercion is low.
