I'm a computer scientist with an interest in evolutionary biology and the nascent science of memetics. Viewed in memetics terms, religions are gangs of cooperating "mind viruses" whose only "goal" is to perpetuate themselves, often at the expense of humanistic interests. I have written and collected a wide range of material on this topic on my web site.
As a rotating co-host of Atheist Experience, I have the pleasure of bringing these ideas to the show. When I am co-host, you will often find me criticizing religions, especially Christianity, on moral as well as rational grounds. Atheism and secular humanism are vastly better than religions in ensuring our survival and achieving our potential as humans.
