From the excerpts, it sounded like she was a bit overdramatic, but I can see her point - she wasn't apologizing for being Christian, she was apologizing for destroying the minds of all those children. And if I had tought children to believe in Christianity back when I was a member of that terrible institution, I would apologize for it, too.
Teaching children to believe in Jesus is one thing. Jesus was a great guy, possibly the son of God (although definitely a different God than the Christian God), and had teachings that everyone needed. I consider him the foundation of socialism and liberalism as we know it today - love sinners, care for the poor, avoid judging others, and give to Caesar what belongs to Caesar.
But Christianity as we know it today has nothing to do with those ideals or that messiah. They follow the teachings of Paul, who is the foundation of social conservatism as we know it today - Paul was the man who said that women should not be allowed to speak in church, the man who said that all authority was put in place by God and we should follow it, and the man who put homosexuality on the same level as gossip and stealing. Modern day Christianity indoctrinates children with the idea of a tyrannical God, it teaches them to do what their pastor says or else risk going to Hell, it teaches them to live by a restrictive "moral" code or go to Hell, and it teaches them that everyone who is not like them is going to Hell, and that it is their duty to similarly indoctrinate everyone else they meet, so that they don't go to Hell. The result is that the child blindly follows authority, associates pleasure with sin, and they are ostracised from the rest of the community and can't see why.
I for one believe that the Bible should not be read to children, at least not the Old Testament. How a book with so many "adult themes" (incest, polygamy, prostitution, murder, adultery...) got a status of being a necessary book for child development is beyond me.
