I knew someone would eventually come along with their opinion, and while you are entitled to your opinion, I completely disagree with you.
First let me state this - I am not gay, nor do I have any relatives that are or any very close/best friends that are. So this isn't personal, but I take it personal. I do have some friends that are though and am very proud of the people they are.
My brother is mentally challenged and will forever have the mental capacity of a 5 and a half year old - it was a medical malpractice at birth, completely the doctors fault. Among many things, he cannot speak like you and I, and is hyperactive, can not sit still for more than an hour. Now my point is is that my brother is 21, he lives in a home and he will never have the opportunity to support himself, go to college, fall in love with a girl and get married, have a baby, even sing a song. Now this isnt a pity party for him, those who love him just want him to be happy and he is and that's all that matters to us.
Point being, I know how many of life's gifts my brother has been deprived of and will be deprived of, and I would never ever want to wish that on someone else. Yes, being gay is different than norm and there is alot of things to figure out when one is gay - the traditional family changes and children have questions. However, there is no such thing as the perfect family anymore - and just because this family is different, does not mean its bad, I'm sure they are a loving and happy family because they are being true to themselves. Being gay doesnt mean that they should live unhappy pretending to be someone they are not.
EVERYONE IS DIFFERENT, whether it is their race, religion, gender, or sexual oreintation. So I'm sure, you yourself are different some how too - would you ever want to create a rule that forbids you from being happy?
I apologize for making this board political everyone
