Might his Excellency help these teens by distinguishing the difference between accepting that "people can be themselves...and love who they want”,  but that sexual acts are for marriage, marriage is between a man and a women, and sodomy is one of the 4 sins that cry out to heaven for vengeance [Genesis 17:20-21]?  Having a same-sex attraction is not the same as ACTING upon that attraction. Sin is in the will. We are not animals, subject to being ruled by our feelings and senses.

From the Catechism of the Catholic Church: http://www.vatican.va/archive/ccc_css/archive/catechism/p3s2c2a6.htm

CC 2357 "Homosexuality refers to relations...sexual attraction toward persons of the same sex... Basing itself on sacred scripture, which presents homosexual acts as acts of grave depravity, tradition has always declared that 'homosexual acts are intrinsically disorded'...under no circumstances can they be approved."

"UNDER NO CIRCUMSTANCES CAN THEY BE APPROVED" (Catechism of the Catholic Church)
