Sorry to break it to you frankiej, but I and I imagine most atheists are well familiar with those verses. Hang around on atheist internet forums for a while and you'll see someone trot them out as examples of biblical injustice. The difference between we atheists and Christians is that we atheists have read that stuff and rejected it, while Christians tend to never have read it and accept it. And when it's pointed out to them, they try to explain it away somehow.
Christian apologetics is the art of rolling a dog turd in sugar and selling it as a donut.
