Growing up in a strong religious culture (though not a cult) that I later became disillusioned with, it almost hurt noticing the same trends in so many other areas of life that one would think immune from it. From sports to academics to social movements.
There is something inside of humans that has for centuries made religion very popular. Even now that many have been able to leave religion behind, what ever that is deep inside of use still exists and it is influencing the new social groups we form, creating systems of beliefs and rituals.
