If someone has made a mistake and none yet have punished them or called them out for it example they dont have full knowledge of someone, so they assume that person is an idiot and rub it in their face yeah you can call them out and let them know hey this person is not an idiot but dont instantly get incredibly rude to them of course if they lie they're punishment will be a shun from the community but if they make a simple mistake or dont understand something so they assume dont shun them you made mistakes too and if you say you haven't we all know you're a ****ing liar
