I do not answer loaded questions especially when they are unreferenced. In any case, Lot fathered children by his daughters, David had a man killed to get his wife, the Bible does not say that those things are OK. If you wish to further discuss this start up a thread with your questions on the religion forum and I'm sure you'll be answered quite adequately.
There is plenty of reference to the Biblical background to those questions in this thread. Clearly you have the right to choose to decline to answer if you wish.
