Tradition is a major part of culture, and it helps people preserve their identity in a society. Different societies have different cultures. Some of the traditions in one culture can be looked down upon in another. There is one vicious tradition stemming from the European nation of Spain that is looked down upon in the modern world.
It is the blood sport called bullfighting. There are several variations, such as running with the bulls, or in general provoking the bulls. This is simply animal abuse, and in the modern age, such things should not be allowed. Despite all of this, traditions are hard to take away.
