Man Ufans - Are They More Than Willing to Help Fellow Man Uphans?

A study involving fans of the manchester united sockar tem found that they were more than willing to step over a liverpool fan. This is a sort of classic tribalism in terms of our empathy and generosity. But i think there's a deeper take away from this study, which is that it's easier to sympathize with people who are like us than unlike us. Each self carries with it a different group, maybe of a different size.
