[[I dont know. Im all for mocking leftists, but that clerk seemed to be genuinely mentally ill.]]
Not so much mentally ill as demonically triggered- it comes from a black soul filled with anger and hate- because the love of God is not in his heart- people like him are what leads to groups like the romans who could skewer Christians in pits and roast them over open fires
but that clerk seemed to be genuinely mentally ill. Sure, all leftists are nuts, but that poor bearded clerk seemed like he needs help/treatment.
Borderline Personality Disorder. Perfect match. The borderline doesnt actually mean marginal but more like hysterical. Yes, there are treatments.
