I just ask myself if I wielding my Karen energy for good or for evil. Because I inevitably have it. I'm a white woman of a certain age, with a certain level of education and entitlement. I can trip into it or access the Karen narrative the moment I express any criticism or anger in public.
Against a waiter or retail clerk? Absolutely not. Against a stranger just trying to live their damn life? No. Who needs that bullshit drama.
Against a cop or an older man, or another white lady, feeling a bit too comfy in their assumed authority? My 'Karen' voice is useful AF.
