Religion today serves no purpose, really. It did at one point, but it doesn't now. As societal animals we've moved beyond the need for religion. Additionally, religion by and large is a (huge) net negative on society. Couple that with the fact that, for instance, internet, business, love do orders of magnitude more good than the rather minor harm and you can't equate religion to the others (perhaps, alcohol and drugs, but even those have more positive benefits than religion).
