I surely have encountered "Karen's", but I really dislike that way of thinking of others people. Most of those that label others as Karen's are lacking empathy and or skills how to deescalate, which I find is sad
Then, please ask again and don't feel bad if someone fails to explain it to you :) If an explanation doesn't make sense it's likely that the one giving the explanation skipped a few steps that they think are common-knowledge, but those aren't.
Where's there a search function on Jerboa anyways, that doesn't only output communities?
