Of the two forces, community is the most powerful - individuality is a luxury of the most prosperous and stable societies. Community shields us against the forces around us. This is where religions come in. Religions use this powerful sense of community more successfully and with greater continuity of purpose than any other human organization. Religions bind individuals together into a community by making them different from others.
Religions promote variation in language, dress, and familial culture.
Clothing makes people especially aware of their differences, hence such great emphasis on clothing in all the religions of the world - favouring also people's natural love of dressing up and feeling important. None of the larger religions is pacifist - for all the noble words. Religions decry war but prosper on it as demonstrated by the success of The National Day of Prayer promoted by the Church of England during WW2. And it is no surprise that societies which allow the individual greater voice are harder to bring to war. I showed that at every period during the 5,000 years of history when men developed a higher culture Atheism appeared.
