Been trying to put stoic teachings into practice and whilst this hasn’t happened yet, I often wonder where we should draw the line between letting things go and standing up for ourselves? Is it my own misjudgment that stoicism promotes a pacifist/turn the other cheek doctrine?

Say a guy disrespects you, surely you speak up, calmly but without hurt or hesitation? Where would the line between stoic and standing up for yourself be?
