That is seriously fucked up. Thankfully, the kid has a way out (lots of strangers stepped up tp help him). Even in 2014, the way things are now, who the hell would choose to be gay considering how much backlash and discrimination you will still face? This cannot be a choice, or not purely a choice. There may be posers like Madonna who pretend for a moment to be "cool", but the people I know who are gay, even in California where they are well protected, still have to look over their shoulders.
I grew up in a household like that kid's, where the "word of god" was all you needed. It is a good thing I am hard-wired to be straight. But even that has a lot of landmines. Oh, you like girls? Think about them? Get horny? You're going to hell for the "sin that cannot be forgiven."
We need to evolve a bit more.
