You guys really need to be careful how you speak to certain people here. Many said this is a troll but how do you know that?
For all that you know, this was a young person reaching out to God and to us, someone who may be now out there on the streets drugging themselves to battle what you believe to be a sin. And regardless of whether this is a sin or not, would you jump like that in them if they confessed to being, say, an adulterer, or a hitman?
A lot of times people get overwhelmed by our responses, when a "welcome, God loves you and is overjoyed you are seeking Him and I love you too" would do.
