How does Mr. Kenney propose to tell parents their kids have joined an LGBTQ support group without "outing" them?  Nobody ever told my parents what clubs I was in at lunch. I wouldn't expect my teenage kids to tell me, not unless they want to. 

 The parents upset at not being told, or whose kids are uncomfortable telling them they've joined themselves, are the ones that are the biggest  hazard to the kids' wellbeing.
