I think the point is that secularism doesn't give you 'instant friends' like religion does. Secularism doesn't have shared culture or common experience to bind people.
For example, there's a 0.5 mile street in the town I grew up in that has 13 churches. This was an area settled by people from around the world, and the churches enabled them to have an immediate extended family when they showed up.
