gay gene

I fully believe that we should look into whether there is or isn't a gene for determining sexual orientation for two reasons.  My first reason being science, I believe that we should strive to know as much as we can know.  Yes there will be the potential to do harm but i think that comes with most knowledge and all though there are those out there who would try and use it in a negative way, i have faith that there are enough forward thinking people in the world to prevent it from actually happening.  And the second reason has more to do with raising the child.  I think it would be wonderful for a parent to know from the time the child is young so they can provide as much support as a child would need given their orientation.  I feel like the potentials always there and some parents end up just being too surprised and don't know how to approach it when they find out if their child gay, not even that but children feel pressured to be one way to keep it from their parents because they are afraid of their reaction.  Wouldn't it be great if we could remove all that pressure from the beginning of a child's life.  Also i feel like if you found out and you didn't want a gay child there's always the option of finding someone to adopt them who will love and support them their entire life instead of just until they come out.  I just feel that there are some positive out comes to finding out that were ignored in class.
