That's not the issue, not sure why you try to steer discussion that way. The issue is, that's not enough to be an asshole and have some respect or general approval for that.
Every Karen making hell for entire neighborhood has some sad story behind, usually series of them and some are properly fucking horrible and heartbreaking to levels where this article reads like great easy chill life. I wish I was kidding, wife is GP and has to do basic psychiatric work too due to lack of available specialist doctors and the stories she hears almost daily... For example the amount of people who experienced sexual abuse as children with lifelong devastating consequences is fucking horribly high, but most go unreported even to close family so not part of any stats.
To condense - this is not enough as an excuse, however harsh the life can be. Thus don't expect that much sympathies. I'd expect a bit higher empathy levels from folks here.
And where's the reaction of Karen using her apathy to harm someone who just wants to get their benefits and not go homeless? Apathy is an emotjon as well.
"Karen" is following procedure. She didn't create it. She's not choosing to harm anyone. The "no email" policy is not hers personally. She's entirely innocent here.
