The correct answer to this open question is the following.
What we can do today as American citizens to protest laws that we consider unjust is to exercise our right to protest, which is supported by the Constitution. We have to do it in the correct way, not in a violent way. We have the right to pacific assemble, to march, and organize demonstrations to show or opposition to injustice laws. And we also have the right to contact our Congressmen to express our unconformity and ask them a reasonable way to resolve things.
