Reasonable person standard applies to all use of force, so no, not really.
The right to protest does not extend to infringing on the rights of another. My right to protest does not supersede your right to leave your home and travel in public. I cannot detain you or deny your free movement.
You do not have a monopoly on the use of public roads, sidewalks, etc. “Taking” the public roads or sidewalks for your private use is not reasonable.
