You're right. Laughing at a situation in which there was no permanent damage and 0 casualties is wrong.
There is nothing that can't be joked about. Nobody is saying it isn't terrible-- we are just making light of it.
Due to lack of displayed empathy I can't expect you to fully understand the seriousness of this but I will try to reach to you the best I can through a metaphor.
I know this may not apply to you, but it may to someone you love, and to each of these people who suffered, their families and friends would certainly have been equally distraught.
First lets imagine you had a severe nut allergy. Like you need to carry an epi pen and wear a bracelet severe. Like you could very well choke to death from your reaction to this event, from even minor stimuli such as the dust of someones peanut butter crackers spraying into the air.
This is a terrible condition and it takes a lot of work to live with such limitations: A lot of foods you can never enjoy, a lot of bars and clubs etc you cant visit because they openly serve peanuts.
Living with this condition you would seek those of which you could confide your frustrations, a place you could be sure was safe and allergen free. You make friends here and have a sense of home. These people share with you coping techniques, recipes to enjoy life without peanuts, experiences and a sense of comradery from this joint struggle of such a limiting life.
One day some hooligans think it would be oh so funny to break in with bags of peanut dust and start running around the room throwing what to you is a deadly reactive substance in the faces of yourself and all your friends. By some amazing miracle things didn't get too bad.
Only you had to stay in the hospital, inducing bills and uneeded stress upon you and all your friends.
Only your only sense of home and peace is now as terrifying and dangerous as your worst nightmare, and if your lucky you wont have trauma-induced anxiety upon your return to what was once one of your favorite places to confide in friends.
Only you nearly bit off your tongue and bled to death and its a fortunate thing you had someone around you who could respond in a way to maintain your safety. Wait no that was a seizure based thing, sorry. I meant choking to death cause of bronchial swelling.
But you see it still applies. Of course replace peanuts with sudden bright lights, distorting patterns, loud sounds. Wait no maybe that's it.
Probably something that could make you get this:
Lets say here you had epilepsy. Do you know how much that would suck?
You couldn't play most videogames. You'd have to duck out of movies with your friends because you knew there would be explosions that could set you off. You'd never visit a nightclub or dance. Your life would have to be a pretty well maintained piece of work and you would need a way to experience safety.
Having that immediately ripped from you would be disturbing and even if there were no lasting physical effects, you would almost without a doubt suffer internally.
