Indigo Children? I had to google them. At at glance it doesn't seem very... um... creditable, so I don't think I'd worry about the association. I'd worry more about it seeming hippy.. like you say, not a strongly negative impression in real life, but not one I'd want to give either. Hm.
Thanks for replying (:
