Unitarian Universalism???

What in the world?? So my son took an online religion test from Belief Net, to see what religion his views were most in line with. And he get Unitarian Universalism. Don't even ask me what it is! I read up on it and its a bunch of NONSENSE! Its basically a "believe whatever you want and everything will be fine" religion. Where did I go wrong? How do I get him back to Christianity? My goodness! I feel horrible!
