A logical Atheist is an oxymoron. Atheism itself demands that reason and logic are false. They do this by denying the existence of the supernatural, but it is only the supernatural than can view the natural objectively, and only the supernatural that can truly reason.
I've always said that atheism requires greater faith than religion, since believers believe that which may ultimately be proven, but atheists believe that which can never be proven.
The supernatural is very hard to explain. Nobody really knows what it is but many people believe it is there.
Left wing atheists tend to be extremely arrogant. They think they know enough about the universe to determine that God almost certainly doesn’t exist.
