I still cannot comprehend the concept of such a drastic punishment of a child who is not making an adult decision. I could understand the parent who rejects an adult child who won't live by their standards. This happens all the time, for example if an adult child is an evil criminal or drug addict. Some parents do not reject their child under any circumstances, some do. And yes, I see a significant difference between a person not accepting a religion vs a person doing very evil things. But the rejection of an adult child, and why or why not, is an argument for a different thread.
But at 14 we are dealing with a child. A child who still needs love and guidance from both parents. Stupid father here who rejects a child for a decision she may still make (or not...but she is still a kid now and deserves a break). Kids, especially teens, make a lot of decisions that don't please their parents, however most grown into good adults despite their youthful errors. (and yes, in this case "error" is used broadly since whether or not she is making an error is a matter of opinion).
Why do they insist on requiring baptism earlier and earlier in life, instead of REQUIRING it to be an adult decision made with some maturity under the belt? Oh yeah..that would be logical....sigh...
