Atheists claim that “the Old Testament still applies” | True Freethinker

Mariano has written a very great post. Here is his introduction:

You may or may not be surprised that many atheists attempt to talk Christians, and other atheists, into believing that the Old Testament still applies (they are unsuccessful with Christians but very successful with other atheists). Three examples of this follow and all such claims seem to focus, or lack focus, upon one text…to which we shall come.
So does the Old Testament still apply? Did it require savvy 21st century atheists to figure out that 2,000 years of Christian have been mistaken about the Old Testament and therefore the New?

The arrogance of atheist who use arguments like this seem to think that the arguments are new and no one has every given good credible answers to them. Mariano's answer is not new but it is powerful. I have never read and heard a good rebuttal to it.
