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.
I’m not sure our definitions of a Karen are aligned. I would say they are overly entitled to a point that is unreasonable, there are many other aspects of people you can combine yes. I don’t think all Karen’s are racists though some are. My point wasn’t about them directly keeping standards high. I am pointing out that they keep the heat off those who do act reasonably by being over the top. If the highest standard was a person asking for a (completely) clean spoon, people may wonder what their problem is, that spoon is clean enough.
