Hatred and violence are bad. I am almost ashamed to write such a naive self-evidence, but recent events in Second Life show that evidence is not the same for everybody. Thanksfully this is only virtual, which must be why such levels can be reached, but still I cannot help thinking about "The Battle For Spain", the excellent book by Anthony Beevor about the spanish civil war : it has already been for real. And it was ugly.
An interesting part, among many, is the description of a speech by Miguel de Inamuno in Salamanca. He adresses the fascists, but maybe we all can learn something :
Venceréis, porque tenéis sobrada fuerza bruta. Pero no convenceréis. Para convencer hay que persuadir. Y para persuadir necesitaríais algo que os falta : razón y derecho en la lucha.
Miguel de Unamuno, october 12, 1936
You will succeed, because you have enough brute force. But you will not convince. In order to convince it is necessary to persuade, and to persuade you will need something that you lack : reason and right in the struggle.
The whole speech, replaced in its original context, is extremely interesting and can be found in this Wikipedia article. It is also a lesson of courage in troubled times.
