Not individually but as a function of society. These people keep standards high, even the ones who are unreasonable. I don’t like them and I would hate to deal with them but in contrast they make reasonable people appear reasonable. If there were no Karen’s you might get attitude for asking for a clean spoon. So have some appreciation for these horrible people.
Counterpoint: Karens intrinsically harm all industries they touch. By creating reactive policies and jaded service workers, they lower the service quality for everyone. Nobody that’s emotionally drained from their soul crushing tantrums can now put in the work to provide the level of service they normally would want to. Instead they foster a hostile environment that makes fulfillment impossible. They’re actually the reason you might get an attitude for asking for a clean spoon. They provide no benefit.
