Sc., "and are therefore not accessible to friendly argument": the implication being that in such cases all disputes should a priori be avoided. As regards religious discussions in general, see note [149] on 16:125 .
Mere disputations are futile. In order to achieve our purpose as true standardbearers for Allah, we shall have to find true common grounds of belief, as stated in the latter part of this verse, and also to show by our urbanity, kindness, sincerity, truth, and genuine anxiety, for the good of others, that we are not cranks or merely seeking selfish or questionable aims.
Of course those who are deliberately trying to wrong or injure others will have to be treated firmly, as we are guardians of each other. With them there is little question of finding common ground or exercising patience, until the injury is prevented or stopped.
That is, the religion of all true and sincere men of Faith is, or should be, one; and that is the ideal of Islam.
