Their duty is to uphold DHARMA NOT to be epitome of tolerance, they are tolerant only towards this goal.
There have been brahmins who have destroyed all the warriors of the earth when adharma had grown ,eg parashuram.
So MR AP brahmins are not in business of being tolerant, they choose to do it if it helps them in uphold dharma and they resort to dharma yuddh when that needs to be done.
