Final answer:
Demonstrations on McDonald's property would be generally false without the consent of the property owner, as free expression rights typically apply to public forums and not private properties like a restaurant.
Step-by-step explanation:
It is generally false that demonstrators are allowed to perform their demonstration on McDonald's property, even if it is peaceful and does not interfere with business. McDonald's property is private property, and the right to assembly and petition, as protected by free expression rights, typically applies to public forums. While public forums can include places like streets, parks, and sidewalks, private property, such as a McDonald's restaurant, is not automatically open for public assembly and demonstrations without the consent of the property owner. Rallies and protests typically require a permit when on public land, and they must be organized in a manner that is viewpoint-neutral and may be subject to reasonable limits to maintain public order.
