(Want to know what all the hubbub is about? Start with Vol. 1)
Because it feeds social narcissism. DBM lets the lucky people who fit in a prescribed demographic stay with people who are a lot like themselves. We like people who are like us, even in the insignificant ways. We don’t have to extend ourselves very far to enter their worlds. We don’t have to explain much. We don’t have to trouble ourselves with struggles that are foreign to us.
The more insulated in DBM bubbles we get, the harder it is to exert ourselves to fellowship with or minister to people who don’t look like us. It’s true that mixing demographics would probably challenge us to show tolerance and patience. Bring it on!
