You're still confusing civil rights for civil liberties. They aren't the same thing.
Our civil rights, life, liberty and pursuit of happiness are protected from repression, by anyone. The "that only applies to the government" argument fails because of what the 5th Amendment says:. "...nor be deprived of life, liberty, or property, without due process of law." A private citizen has no authority to force his will upon another person. There's nothing in 5A that says that only applies to the government.
