I believe gay people are born that way and for many they struggle with their faith sometimes for years. No one would choose to be gay with all the bigotry as well as sometimes even family may treat them differently.
Ive heard about the positions some gay people take [no pun intended] in reference to bible texts .
In ancient societies a family had the responsibility to bring ups family to support fertility in the society and a same sex couple would be looked down on as shirking their responsibility.
Another position taken is a gay couple relationship is normal to them and bible texts are talking about promiscuous relationships.
