Quoting Katie Monster!:" I love reading post where people go ape smurf over things like this.. If she names her girl a boy name, ... [snip!] ... girl name. If I have another little girl someday, her name will be Keegan. I've recieved plenty of bad comments for that one..."
Just as she can name her kid whatever she wants we have the right to say whatever we want about the name if she posts it publicly. She asked for opinions, you can't expect people to sugar coat their opinion because someone might get their panties in a bunch.
