1 - There's a very simple action that can be taken which is boycotting companies and entities that organize or support Bullfights.
2 - Grafittis are a nice urban art form. And they draw attention from the people in the street.
3 - Talk about the matter.
Never leave an opinion in favor of Bullfights without an answer.
For as much as we respect an person that's in favor, it's always important to show that are things that can't agree with.
Most of the times, there is a stereotype in those people who are in favor of Bullfights, result of some specific locations' education. Changing someone's opinion is really hard, but talking about certain matter stimulates the conscience about one's positions.
Step by step mentalities will change and evolve.
