Its possible that there were extenuating circumstances. Women were extremely insecure in those days. You were then put out the door with the clothes on your back. If you didn't have family or friends to take you in, you were in deep trouble. In desperation, some women turned to prostitution.
Some girls grow up without the love and affection of a father.
Their fathers abandoned or ignored them. The last emotion those girls need to experience is condemnation. I don't know who wrote the following lines but they express the feelings that most of us have experienced. How I wish there was some wonderful place Called the land of Beginning Again. Where all our mistakes and all our heartaches And all our poor selfish grief Could be dropped like a shabby old coat at the door, And never be put on again.
