Amongst his popular published output on zoology, biology and evolution his latest work, The God Delusion, is concerned primarily with religion, belief and the effects it has, and has had, on society, and why such should be considered anathema to those who value life.
Dawkins' outspokenness against various aspects of religion have been seen by some to be quite aggressive. He is famous for his opinion that labeling children with the religion of their parents is tantamount to child abuse, and for comparing the spread of religious beliefs to viruses.
Dawkins coined the term "meme" to describe how ideas (notably, religious belief) are spread and evolve using mechanisms similar to those of biological evolution.
