I think there is nothing more stifling, insular, and cloistered than an Adventist "ghetto".

But many Adventists thrive by being wrapped in this cotton wool environment.

The ancient Israelites were similarly insular.  It amazes me that after the crucifixion followers of God/Christ were commissioned to go out to all the world to recruit new converts.

How was it that the Israelites, who had the true knowledge of the one and only God, never were commissioned to proselytize and spread the Word to neighboring tribes?  Their only instruction was to commit genocide against their neighbors!

Adventists in ghettos, may donate funds to spread the gospel, but other than that, they are doing little to evangelize the world if they are in quarantine from their ".unholy " and "non Adventist neighbors.
