I think this rape issue in the bible written thousands of years ago is problematic if you go by the same standards today. Back then and even today(among those who follow a bronze age male Deity) women are to be dominated and are considered property, it worked back them as that was the mind set in the majority of mankind at that time.
Today things are vastly different as women can vote, get equal pay, and equal rights in many countries all due to increased understanding of our world. Staying back in the dark ages are religions like the Watchtower Corporation who take things literally and feel they should be enforced on modern man to make the Deity happy.
