Thank you for sharing about the Philippines, but that isn't quite the same as it notes in the article.
As for the rest, its nonsense. You also overlook the rights of audiences, organizations, and governments to conduct their assemblies for the intended purpose. Your right to free speech doesn't allow you to prevent others from engaging in theirs. You are simply embracing another form of censorship, an attack on free speech, and one popular with fascists by the way. There are 8760 hours in a year. A limitation during 2 of those hours as to where you protest so as to allow another free speech event to take place for the intended purpose is a minor burden at most even if it is worth discussing and some of them go too far. The much bigger problem is what goes on in college campuses.
