Sure, each human has their own unique (in a way) temptations. But the causes of homosexuality are known for the most part, as described in the link (with attendant links) that I posted above. Another point is that homosexuals know that they are recruiting. It is known in the "gay community" that they can make boys into homosexuals. They do it on purpose.
I disagree -- it sheds light like the sun itself. To fall into a hole, one needs a hole as well as to approach that hole.
