Even as a small child, Bill preferred to ask questions before believing things people told him and, although raised a Christian, by the age of 13 he concluded there were no good reasons to believe in God. Bill pursued a career in IT, marketing and management consultancy and thought little about atheism until the 9/11 atrocity showed how religion could become lethal. This spurred him to engage in online debates with Christians and Muslims and to become active on Facebook; debating, creating memes and writing articles. His online presence resulted in speaking invitations from atheist groups in several countries including; India, The Philippines, Ghana, Nigeria, Zambia, Namibia, Kenya and South Africa. This work has developed to the point where Bill acts as a mentor to emergent atheist groups by advising on everything from organisational matters to debating techniques, PR and media training. Bill teaches and promotes Street Epistemology as a way to help people to examine, and revise, their beliefs in a friendly and non-confrontational way.
