I have been watching this thread to see what peoples views are before I say anything.
Firstly, I am slightly offended mainly because of the phrase "the way they have turned out". Now then, this particular phase tends to be used in a very negative way ie Mrs Smith must be devistated at the way her son/daughter behaves or has turned out. Indicating Mrs Smith's child is not an upstanding member of society in one way or another. Mrs Smith's child probably had a choice in their behaviour.
Gay people do not "turn out". Many will struggle and battle with themselves until they finally accept who they are. Sadly, many never do and either live lonely lives or end their lives. Our sexuality is not a choice it is part of who we are, our genes etc.
Yes, life would be easier if we were straight, it would be one less thing for the rest of society to have to deal with. but we're not and people have to accept it, just like people have had to accept some people are white, some black, some have blue eyes, some brown, etc etc. Our skin, hair and eye colour is not a choice, neither is our sexuality.
