This has become increasingly common as the "main stream" christian churches lose members to evangelical one offs. Baptist, Congregational, low Episcopal, and all the others have been hemorrhaging membership for years. About 1/3 die, another 1/3 just kinda leave and go no where else, and the last 1/3 have gone to these kinds of places.

These kinds of Churches are where radicalization happen. Thankfully CT is near the bottom of the list of "most religious states" so these nutjobs should be more or less contained.
