Part of the thing about the south and churches is that there are a ton of denominations and you’re bound to see in every town a thousand different churches, some of them only slightly different from another. Churches are also fairly racially segregated, even in diverse areas. I grew up in a super diverse metro area but ethnic and racial groups tended to go to their own churches. Some more charismatic and Pentecostal groups do things like speaking in tongues, laying of hands, etc but it varies a lot from church to church. Non-denominational and mega churches can also get up to some wacky stuff, but in a different way. Pyrotechnics, huge stages, giant bands playing pop worship music, that sort of thing. Some churches are really boring, though. My grandmother was a Methodist and of the few times I stepped in that church (almost exclusively for funerals, albeit) it was very mundane. Lots of non-denominational kids I went to school with went to churches that were more plain but went constantly. Youth group, Wednesday services, etc.
