If someone laughed at you if (for example) you got knocked over by a bike on the pavement and you ended up sprawled on the ground with your skirt over your head and your knickers on show - wouldn't you berate them for that?
You have to be on something to think there aren't circumstances where laughing can be disrespectful, rude, inappropriate. This is the third instance that springs to my mind with Meghan: first was when she was on the balcony at BP and a horseman fell off his horse. Harry looked horrified, she sniggered behind her hand. Second was at some hockey match in Canada last year where the national anthem was sung by a young autistic girl. Harry stood respectfully and listened to the anthem, Meghan semi-snorted and tried to catch his eye to share the joke until she realised she was being rude and stopped.
Do you think it's off to "berate" someone for this behaviour? Or would you rather just have a go at people telling things as they see them wrt Meghan Markle, for whatever reason?
