In a free society, the only actions that would be crimes and prohibited would be actions that hurt others, harm their property, violate their freedoms, or force them to do things they don't want to do.
So things like murder, theft, vandalism, and breaking contracts would still be crimes. But things like smoking in a private restaurant, not wearing a seat belt in a car, or carrying a weapon for self-defense would not be a crime.
But American democracy is a system where someone is always trying to get control of the government so they can make rules to stop people from doing things they don't like, and force them to do things they do like.
There are usually just two sides to vote for, the democrats and the republicans. Both sides want to force their ideas on other people who don't agree with them. So they want to make laws to keep people from doing things they think are bad like I mentioned earlier. And they want to force people to do things against their will, like fight wars all over the world, help countries like Israel buy nuclear missiles, and spy on their friends, family, and neighbors.
This isn't to say that some of the ideas aren't good. But if they are good ideas that people want to support, they shouldn't need to use threats of force, violence, and theft to accomplish them. People can voluntarily support ideas they agree with and try to persuade others to join them by presenting the benefits of the ideas.
Using government to force your ideas on others is immoral, unjust, and just plain wrong.
