The most optimistic lesson I've learned during my time here on earth is that protest works.The saddest lesson I've learned over the past 20 years is that violence works.
Maybe you're right, persistent organised violence against a peaceful group like a cycling team will work exactly as intended. Many just want to give in until it stops, siding with the organised violence. If only the victims would disappear, the conflict will end.
The sadness of the lesson is that it eventually gets learned by all sides.
Think about how far we have come as a society. Advances in human rights are mainly due to public pressure.
It's the only thing non-elected people have in a democratic society to metaphorically slap the heads of officials to wake them up. It might be members of the UCI; it might be members of parliament; whoever it is, people have a right to share their disgust with things that are going on. I believe that is an essential element of a democratic society, and I'm honestly baffled that people think otherwise.
