LOL, right. If you can't name specific congregations, you're just blowing smoke.
Check almost any CofC congregation in the state of Indiana to find out their own requirements for membership, and what their history of outreach is.
Ought to be an interesting trip for you.
And beware of churches who formerly had a very New England Puritan structure (and belief) and have now renamed themselves CofC.
The CofC with which you are familiar in the Souf' is barely representative of a third of the CofC congregations in this country.
Your narrowmindedness and provincialism is not evidence of ignorance on the part of others, or of lies.
