I would never suggest that anyone, when asked for evidence, reply with, "Google it." It is the ultimate non-thinking, foolish-appearing, answer which makes it fairly obvious that the person does not have a clue.
Evidence for David/Jonathan engaging in sex is non-existent. Contrary evidence?
1. Jonathan was married to a woman and fathered several children.
2. David was married to several women and fathered many children.
3. David's great sin was an adulterous affair with a beautiful woman.
The nauseating suggestion about Ruth and Naomi also has not one ounce of supporting evidence. However, we do read that Naomi was married and had three sons. We also read that Ruth married TWICE, both times to men, and bore children. Her relationship with Boaz is actually the primary element of the Book of Ruth.
When do these responses of yours become embarrassing to you?
There is no evidence at all that gay people are born that way. I would agree that many of them did not choose to have those attractions, just like many child molesters do not choose to have their attractions, nor do those who like having sex with animals. Having an attraction does not make it normal or desirable.
Your question about being left handed is simply foolish. It is not at all a moral concern and there is not a whisper about it being a sin in the Bible.
