Which person is more tolerant?

Person B reserves judgment. Person A is judgmental; they may not insist others agree with them but still compare others' views to their own and that comparison is an obstacle to tolerance. Everyone holds views they believe are right or at least preferable to others. Therefore, your statement in Person B that no view is any more right than another's makes tolerance an issue of philosophy. I submit to you that tolerance is about attitude; it's a simple matter of grace. One can hold to their preferences lightly and still hold to them but manage the relationship between heart and mind so as to not become judgmental, which is the natural outcome of being dogmatic. This is the problem Christians here have: they are so obsessed with being right, that they cut themselves off from kindness and are, therefore, unable to show it to others.
