There are other interpretations of turn the other cheek.

From Wiki:

A figurative interpretation relies on historical and other factors.[1] At the time of Jesus, striking someone deemed to be of a lower class with the back of the hand was used to assert authority and dominance.[2] If the persecuted person “turned the other cheek,” the discipliner was faced with a dilemma. The left hand was used for unclean purposes, so a back-hand strike on the opposite cheek would not be performed.[3] The other alternative would be a slap with the open hand as a challenge or to punch the person, but this was seen as a statement of equality. Thus, by turning the other cheek the persecuted was in effect demanding equality.
