Based on his photo, Christian, a gay birder illustrator, looks about as unthreatening as can be (he actually bears a passing resemblance to me if I were not a person of no color).
Christian is enjoying some bird watching in a place where dogs must be leashed. Karen has her dog running around unleashed. Christian says you have to leash your dog. Karen goes all Karen. Christian says if you don’t leash your dog as required I’ll do something you won’t like. He says he meant by this he’d give the dog a treat which he’s found induces dog owners to leash their dogs for fear of having their dogs take treats from strangers. And proceeds to record the scene. Threatening? Show me a knife. Otherwise, not hardly under the circumstances. Karen not only goes mega-Karen, she decides that To Kill A Mockingbird was not a cautionary tale but an instruction manual.
Karen, the embodiment of the virtue signaling, for thee but not for me, bigotry of low expectations crowd predominant in Manhattan and similar oases, can kiss my ass of no color.
