Among the scenarios you provided, the situation that would likely be considered an exception to the right to peacefully assemble is:
A group of people protesting increased fees block the entrance to a bank.
This is because blocking access to a public or private space can be seen as obstructing the rights of others, which can lead to legal consequences, thereby making it an exception to the right to peacefully assemble. The other situations, although controversial, generally fall under the right to assemble peacefully without blocking access to others.
