6. why does dr. king encourage the white ministers to “let him march sometime” when referring to his protests?

Quote:
'The Negro has many pent-up resentments and latent frustrations. He has to get them out. So let him march sometime; let him have his prayer pilgrimages to the city hall; understand why he must have sit-ins and freedom rides. If his repressed emotions do not come out in these nonviolent ways, they will come out in ominous expressions of violence.'

Herodotus taught that absolute right and wrong did exist.
