You don't even understand what it means to be gay, you ignorant fool! I don't either, but having gay friends, it allows me to grasp the concept better than you obviously have. Alevok made a point about keeping children away from "adult art", and if the times changed, there might be more "gay" art that a child could be exposed to. (although I don't understand the relationship between gay marriages and gay art...

)
My point was that keeping your child from learning/understanding something, will only fuel their curiousity as to why it was kept from him/her. This is why schools now have sex education classes in 4th grade. This is why they tell you to explain to your children the dangers/negative effects of drug/alcohol abuse. People wonder why kids accidentally shoot themselves with Daddy's gun. Well, if all you do is keep it hidden away, don't let them explore and understand it (empty of course), and don't explain the dangers and risks of playing with a gun, he/she will be more curious to explore it on their own, which could lead to dire consequences. If you shield your child from homosexuality and don't explain to him/her what it is or how it happens, then your child will only be more curious about it, and depending on their personality-type, they may be compelled to explore it, especially during that confusing period of life called "puberty". Puberty already jacks up your hormones, and hormones can impair judgment. I assume you can put 2 & 2 together...
BTW, what would you do if your child was born gay? You saying you'd repress those emotions and confusion for him/her, so that when they do discover what they are on their own, to have them disassociate themselves with you for making them feel bad about being gay? Not to mention the fact that if your child feels uncomfortable about their sexuality around you, that you can never be truly close to your child, and that, my friend, would be a **** shame...
