Again with the irony andy, suggesting that I need to "calm down". You're the one posting hyperbole and fear mongering saying that the school's sex ed curriculum is leading to "gender reassignment surgery".  Seriously? What next? You worried that dancing will lead to sex standing up?

Curious that you're now talking about "christians" and not "Catholics" when the topic here is Catholic schools. There are numerous Christians who support LGBT rights and equality. There are also Christian fundamentalists including such extremist groups like the Westboro Baptist Church who very clearly do vilify homosexuals. To claim otherwise is either wilful ignorance or self delusion.

The Catholic Church has this to say: 
"homosexual acts as acts of grave depravity"
"homosexual acts are intrinsically disordered"
"contrary to the natural law"
"Under no circumstances can they be approved"
"is objectively disordered"
