First of all, as a native Louisianan I can comment on my home state....
Most tourists who come to New Orleans for Mardi Gras go away with STD's, so getting Covid-19 is just another in the list of things they need to be careful of when they visit the City that Care Forgot. Only difference is the condom for cover-19 is a LOT bigger.
As far as that church is concerned, well, Louisiana has VERY different areas within its borders....southeastern Louisiana has Mardi Gras, drive-thru Daiquiri shops, and a very laissez-faire attitude left over from the French and Spanish days. Northern and some areas of western Louisiana have bible-totin', no alcohol drinking saints (or sinners) who look at life TOTALLY differently. Those folks don't recognize Jews as religious people, don't recognize Yankees as Americans, and don't recognize each other in the liquor store. We don't really claim them as kin where I come from.....what can I say?
