Answer:
Social movements should all have a point. For example, this social movement wanted to help women's rights, here they had a point. In todays world people should have the right to march, and speak, because they want something to change for the better. As long as you don't hurt anybody while protesting, it should be fine. We call this a peaceful protest. I would join a social movement if it effected me or if I thought something needed to change. I would do the exact opposite if I think that everything is fine and nothing should be changed.
