Stay safe out there. Take precautions to insure your safety and health by wearing a mask to prevent airborne viruses that may be present in large crowds. Don’t use poles or sticks that can be interpreted as weapons to hold your signs. Use an old phone or other device to document incidents instead of the phone you’d normally carry. There will be agents of chaos out there looking for excuses for violence.

The First Amendment of the United States Constitution protects the right to freedom of religion and freedom of expression from government interference.

It prohibits any laws that establish a national religion, impede the free exercise of religion, abridge the freedom of speech, infringe upon the freedom of the press, interfere with the right to peaceably assemble, or prohibit people from petitioning for a governmental redress of grievances. It was adopted into the Bill of Rights in 1791. 

The Supreme Court interprets the extent of the protection afforded to these rights. The First Amendment has been interpreted by the Court as applying to the entire federal government even though it is only expressly applicable to Congress. Furthermore, the Court has interpreted the Due Process Clause of the Fourteenth Amendment as protecting the rights in the First Amendment from interference by state governments. 

Freedom of Religion
Two clauses in the First Amendment guarantee freedom of religion. The Establishment Clause prohibits the government from passing legislation to establish an official religion or preferring one religion over another. It enforces the “separation of church and state.” The Free Exercise Clause prohibits the government, in most instances, from interfering with a person’s practice of their religion.

Freedom of Speech / Freedom of the Press
The most basic component of freedom of expression is the right to freedom of speech. Freedom of speech may be exercised in a direct (words) or a symbolic (actions) way. Freedom of speech is recognized as a human right under article 19 of the Universal Declaration of Human Rights. 

The right to freedom of speech allows individuals to express themselves without government interference or regulation. Generally, a person cannot be held liable, either criminally or civilly for anything written or spoken about a person or topic, so long as it is truthful or based on an honest opinion and such statements.

The right to free speech includes other mediums of expression that communicate a message. The level of protection speech receives also depends on the context in which it takes place.   

The right to freedom of the press guaranteed by the First Amendment is not very different from the right to freedom of speech. It allows an individual to express themselves through publication and dissemination.

Right to Assemble / Right to Petition

The right to assemble allows people to gather for peaceful and lawful purposes. Implicit within this right is the right to association and belief. The Supreme Court has expressly recognized that a right to freedom of association and belief is implicit in the First, Fifth, and Fourteenth Amendments. Freedom of assembly is recognized as a human right under article 20 of the Universal Declaration of Human Rights. 

This implicit right is limited to the right to associate for First Amendment purposes. It does not include a right of social association. The government may prohibit people from knowingly associating with groups that engage in and promote violent or illegal activities. 

The right to associate also prohibits the government from requiring a group to register or disclose its members or from denying government benefits on the basis of an individual’s current or past membership in a particular group. 

There are exceptions to this rule where the Court finds that governmental interests in disclosure/registration outweigh interference with First Amendment rights. The government may also, generally, not compel individuals to express themselves, hold certain beliefs, or belong to particular associations or groups.

The right to petition the government for a redress of grievances guarantees people the right to ask the government to provide relief for a wrong through litigation or other governmental action. It works with the right of assembly by allowing people to join together and seek change from the government.
