Khandro, there are many children who, for various reasons, don't have a mother or a father, but they do have other people in their lives - aunts, uncles, grandparents, friends - and those children do grow to become what they are, be it heterosexual or homosexual. They just do. Oddly enough, another friend of mine was married - she thought happily - for years - until her husband ran off with another man. Her two children, a boy and a girl, were young adults when dad disappeared, and are both gay. Dad certainly didn't influence them in that direction - so something in the genes … possibly?
My real problem with your attitude though is your assumption that all gay men are paedophiles. Have you considered my question 'Why would they be?' Of course we get paedophiles who prey on children - male and female - gay and straight - but that's because they're paedophiles. You're attracted to adults so why do you assume that the majority of gay people aren't - just as the majority of straight people aren't?
