I would like to put on paper the main points of the conclusion I reached on that occasion. I believe they may be a good start for a philosophy of inter-religious dialogue. Respect is not conditional. It is not earned by virtue and it is therefore also not lost by vice. Because it is not conditional, it is not subject to change.
Respect is intrinsic to a person's quintessential humanness.
From a religious perspective, man's free choice means he was created in the image of God. This is true of all humans and is the most profound basis for mutual respect. This respect has no borders. It applies even to criminals. Not because you consider them a victim of a pathology as some psychiatrists do, but because evil as they may be, they are still human.
