One of the most efficient ways of defining the freedom of speech is the word “demonstration”. I always admired the march of people who are finding a peaceful way of expressing their view on different issues, even when I disagree with their opinion. So it was a pleasant surprise for me this last Sunday to stumble upon a demonstration on one of the main boulevards of Madrid, Gran Via. The issue in cause: the freedom to fish, and sometimes release, a number of predator fishes in the Spanish rivers. I tried to find out more about the debate, and these were my findings.
