I don't see burning the image of a saint as a lesson from Krishna to make us tolerate that offense. In fact I really dont consider humility to be the tolerance of a saints image being burnt. Humilty is defined differently in the scriptures I read, and duty is likewise defined differently. Tolerating offenses to others is really the opposite of humilty, it is more like cowardice, and by remaining silent we become guilty of that offense.

If someone comes and beats your neighbhor with a stick, its pretty easy to "tolerate" that and hide, the hard thing is to stand up and help that person.

The Bhakti Rasamrita Sindhu never states that we should become humble by tolerating offenses to our saints.

In fact in the history of India, this is the first time the image of a saint has ever been burnt. It has never happened in the history. What this shows is that Kali Yuga has managed to increase its influence on the world.
