Tolerance is refer to differences (ideas, life style, etc.), not to offence, abuse or injustice. (The “tolerance” to latter is better to be defined as “forgiveness”.)
Tolerance to injustice is the best “gift” humans offered to Evil. It does help injustice prevails.
A healthy relationship is built on understanding, or accepting/embracing (without understanding) each others’ differences, NOT on one-sided tolerance to mistreatment, or abusive behaviors.
If violence were not avoidable, I rather see guilty persons punished by violence, than seeing innocent people keeping suffering by never ending violence that escaped by “tolerance”.
