If the principle from the bible supposedly said by Jesus is to be abided by, then there is no room for witnesses to be "non-practising gays"
They say "you cant even think it in your heart". This has nothing to do with acting on those desires.
So the premise said above that a "gay" person can be so but just cant practice it is false.
As a witness once said "you cant be a racist in your heart, because God still knows your thoughts, and one day you will act on those feelings anyway"
