For Susanna LaVelle's parents, watching their 11-year-old daughter make her big debut was a moment of heart-swelling pride.
But the LaVelles weren't attending a child's soccer game or ballet recital. They were gathered outside of a sports arena in Spokane, Wash., for their favorite pastime -- preaching from the sidewalks that the people filing in were sinners with a one-way ticket to hell.
And for the first time, their daughter Susanna was taking the microphone to spread their message by herself.
"Blessed is the man that walketh not in the counsel of the ungodly, nor standeth in the way of sinners," Susanna yelled at fans heading into the arena to watch a college basketball tournament. "You must repent. Turn from your sin. You must turn from everything, drinking, pot smoking, everything. You must turn from your sin."
Susanna's mother Kristenea LaVelle said the "wonderful" moment "brought tears to her eyes."
"I thought it was fabulous," she said.
Her father David LaVelle was by Susanna's side and took his turn sharing his religious message with arena patrons.
"I know your conscience testifies against you every time you look at pornography, every time you look at things on the Internet that you shouldn't look at," he said.
An engineer by training, David LaVelle is one of the leaders of a group that calls itself the Spokane Street Preachers, a controversial band of sidewalk evangelists pushing the boundaries of tolerance and free speech.
"Nightline" spent 48 hours following the street preachers in every aspect of their lives. The LaVelle family is the heart of the group, not just because parents David and Kristenea LaVelle are so active, but because they have 11 children, ages 1 to 21, who all train for the day they will make their preaching debut.
The Spokane Street Preachers' fundamental belief is that churches today preach a candy-coated, watered-down message designed to skirt some sins to appeal to a broad audience. They say that preaching at people is no different from a person yelling at a child who ran out into the street without looking both ways. They said they are just trying to keep people from going to hell.
The street preachers don't just hang around outside of sporting events. They practice equal opportunity intolerance, picketing outside of Planned Parenthood centers, Catholic churches and Islamic centers.
Standing outside one of their favorite targets, the Spokane Islamic Center, they use the megaphone -- one that is so powerful it's designed to be heard across the noisy deck of an aircraft carrier -- to preach things like, "this religion of Islam says that my Lord and savior is a liar" and "Allah never gave his life for you...all Allah gives you is rules."
Again, the LaVelles don't believe what they are saying is hateful, only helpful.
"We are speaking the things so they will be woken up," David LaVelle said. "What is hateful about telling somebody the truth? I am not seeing the connection between preaching the truth and hatred."
And if someone were to show up outside of his house and started shouting their beliefs at his family, LaVelle said he wouldn't be fazed.
"We do have freedom of speech here," he said. "I would go out to them and talk to them and tell them it is not true… in fact, I might welcome it."
