Sometimes they march to an army cadence kind of call and response thing. "Jesus!" "Say what?" "Jesus?" I guess you can march to it.
Sometimes they do it in Spanish. I can understand it. (Not complicated Spanish.) I prefer that. I can tune it out. The sound does not snag my ear so.
During my time in the South I got very intolerant of people telling me about my sins. And i got quite fierce about having that directed at my kids. My kids are big now, but the feeling remains.
