Has nothing to do with church. Black neighborhoods are always shuffling new people in and out and getting gentrified on top of that. You don't really care to get to know your neighbors like that when every year a family is moving out the neighborhood and being replaced by a new one. The turn around time in the neighborhood I grew up in was 5 years and my parents are now 3 houses removed from where I was raised. I don't know anyone in the neighborhood I grew up in that still lives there.
I'm just as bad. Lived in a different apartment every year until I bought a house. Lived in this house for three years and will either sell or rent it out in the next two years. I don't know any of my neighbors because I'm now the longest tenured person on my block. And judging by how my girl is, we'll prolly never live in the same neighborhood for longer than 10 years

. That's not community building at all.
