Pro-Life Christian did not know what abortion was...?

.A little kid I know is unfortunately being raised by evangelical Christians. His parents are having him wear this anti-abortion t-shirt, which is kind of messed up but anyways. The other day, while wearing this t-shirt, he asked me what abortion was. His parents filled his head with all this anti-abortion **** and never even bothered to tell him what it was he was protesting. Does no one else see it as wrong to use children to push your own agenda???? I don't know, I was always taught that it was a bad thing to use children for your own ends. Maybe they don't teach this in the average American Christian household
