Why are first amendment freedoms not absolute freedoms?

One kind of freedom can conflict with another kind of freedom, or it can conflict with legal responsibilities. Absolute freedom overrides everything, it can have no exceptions, and that is impractical. For example, there are many ways that free speech can be harmful. We do not allow fraud, slander, false advertising, or copyright violation, even though all of those are forms of speech. Society will respect someone's rights if that person will respect other people's rights in turn.
