^ Your last para sums up my thoughts. I’d feel sorta guilty if I turned a blind eye to it but then the fear of being labelled something not-so-nice would make me mind my own business.
I don’t get the reason for being so furious though. I’ve been corrected about everything from keeping some distance between my feet to getting my hands position right to making sure my nose touches the ground during sajdah… and it was OKAY, whoever corrected me wasn’t trying to be holier than thou or anything.
