Kids at 1,231 schools and colleges have taken a vow of silence on October 18 — as they stand in solidarity with unborn kids in danger of being aborted.

Many will go to school wearing a piece of red duct tape over their mouths. Where did such an idea come from? Here’s a video giving a bit of history:

Others will wear red armbands and carry fliers explaining why they are silent — educating others about the plight of the innocent children lost every day.

“One girl wrote in to the Day of Silent Solidarity team last year, saying that when she arrived at school, a fellow student came up to her and said she was wasting her time and that no one would listen to her. ‘All I did was nod,’ wrote the student, ‘and gave her the paper [flyer],’ at which point she ‘threw it at me.'” reports Jeremy Kryn for LifeSiteNews:

But when the pro-life student walked away, she said that she saw the other girl pick up the flyer and put it in her pocket. Later that day, she said, “I saw her but her eyes were puffy, then she hugged me and said I was making a huge difference to a lot of girls, and that she was scheduled for an abortion later this week and that she will cancel it.”

The pro-life student concluded saying that she feels “happy to know that not even saying something made such a difference.”

Another student, Lyssa, described how when she entered the school wearing a pro-life t-shirt and the red duct tape, a bunch of students at a nearby table were murmuring about it, and “one of the guys came over with clear duct tape on his mouth, trying to mock me.” But by lunchtime Lyssa had convinced 25 other students to join in the Pro-Life Day of Silent Solidarity effort.

What if students run into official resistance at school? Attorneys for the Alliance Defense Fund are encouraging students to contact them for legal backup.  And the organizers are asking any student intending to participate to register at the SilentDay website.
