I literally just said a peaceful manifestation without violation of the other’s right is possible and has been done not even too far back.
And also, these “Piquetes” aren’t peaceful at all. It is violent to stop workers from going to work, threatening their income necessary to sustain their life, it’s a crime under the hood of enforcing a right and that’s why they should be repressed. Those who don’t incur on the people’s freedom to go to work and live peacefully shouldn’t be of course.
