The First Amendment to the Constitution prohibits the government from infringing upon the freedom of speech, the freedom of association and the freedom to petition the government for a redress of grievances. Speech is language and other forms of expression; and association and petition connote physical presence in reasonable proximity to those of like mind and to government officials, so as to make your opinions known to them.
The Declaration of Independence recognizes all three freedoms as stemming from our humanity. So, what happens if you can speak freely, but the government officials at whom your speech is aimed refuse to hear you? And what happens if your right to associate and to petition the government is confined to areas where those of like mind and the government are not present? This is coming to a street corner near you.
