Some humanoids disagree with these people's beliefs so there have been mass protests and even assassinations. Just like the Kennedys.
Sometimes animals will share this belief, such as anger cows and anger mullets.

You can often see them hanging out in mass crowds at your neighborhood pet shop or THE British Brewery.
