How would the situation be reversed in your analogy? In your little scenario the 11 yr. old is being told an outright lie. This suggests that you believe the girl's uncle told her a lie. Care to explain yourself? Maybe you're not as pro-life as you claim to be.
See #49. By "reversed", I mean that it is not appropriate for an adult to try and undermine the relationship of a child and her parent, even if we know we're on the right side. I disagree politically or fundamentally on many issues with certain family members or friends. This does not give me license to make their children question their authority or love. It is simply wrong to drawn an 11 yr. old into a situation like that.
Maybe you're not as pro-life as you claim to be.
My pro-life stance is pretty well documented on FR. I can understand people siding with the uncle, because I know he's on the right side of the issue, but I do think his actions with the 11 yr. old were wrong.
