Exactly. For the past month I've read many people here saying protest are useless because of various bullshit reasons. Protest are just a starting point. At protest, people talk, organize, that can lead to more massive protest, a new ideology, a revolution, or nothing. You never know.
I'm French. I have been to many protests. Some ended in massive movement for no reasons. Some died while the cause was very important. You never know.
