Despite the initial uproar, the turnout was modest, and Gibbs and others took to Facebook to voice their disappointments.
"I do so love how Northlanders get fired up about something and then do dick about it," Gibbs posted on the page.
Donna Reddish agreed. "Yep I know, I drove past saw no one there too so didn't stop."
Others were less enthusiastic about the protest.
"If that was my fence, I'd ring the police and press charges of graffiti/vandalism," said Shaun Walburn.
"The church isn't hurting anyone ... What a load of whining liberal claptrap."
A member of the Bay's gay community said she was saddened by the seminar and the idea that gays had to be cured, but she also felt sorry for church members who were following their own beliefs.
Pastor Bill Anderson earlier expressed his disappointment in the attacks on him and the church.
