Yes, she is a new-age "parent." Rather than helping to reinforce school rules and order (do schools even have rules anymore?), she openly and flagrantly allows her daughter to be a disruption by endorsing her behavior.
Take a peek at the child. Does she really look like her mother has taken any time with her ?Paid her any attention at all? Her only way of attracting any attention is to wear a sign saying she is queer. The other kids hanging around her appear to be a little on the strange side too.
