How does the bill of rights ensure that the us remains a democracy?

The First Amendment in the Bill of Rights states that every United States citizen has the rights to freedom of speech, freedom of the press, and freedom of assembly. With these freedoms we have the ability to share our opinions and vote on how our government should be run. Democracy is a form of government in which the people of a country either rule directly or through elected representatives, the Bill of rights gives us the ability to state why we do or do not like how our government is run and it also allows us to express what needs fixed.
