Hildy is entitled to live her life as she pleases; she is not entitled to support and affirmation from people that disagree with her choices.
What does that mean?
No, but that post in response was specifically intended to make her feel bad, for making a choice the other poster thought was "wrong". This is one area in which there really is no right or wrong, where people can and must judge for themselves what is best, rather than doing what others think is "right".
