It is nearly always assumed that when two persons (or parties) are discussing what course of action would be better - they both mean the same by 'better'. This gets assumed; and then the conversation focuses on the means to achieve that end. This is pretty much how mainstream politics works.
But what if the 'better' on one side includes or concentrates on aspects that are denied or regarded as trivial or even wicked by the other? Then, all conversation from that point onwards is futile - and indeed actively misleading.
That is the current situation that the mass media call 'polarisation' of public opinion - it is a situation of different ends, rather than merely different means. It means that one course of action is going in one direction (or intending to), while the other course of action is aiming in a different - perhaps opposite - direction.
When this is at the level of materialism then that is severe enough (eg open-ended mass immigration a positive or negative thing?); but when one side focuses on spiritual goals that the other side regards as nonsensical and non-existent, deceptive or delusional... then the situation is as extreme as can be imagined.
Different sides are then so different that the is very little possibility of compromise - except by accidental overlap, with respect to minor things.
This will affect all human interaction, from small talk to formal discourse about serious matters of law and national policy.
The proper response would be to discuss these fundamental differences, and their reasons: the proper response would be to engage in metaphysical discourse.
Indeed, that is non-optional.
So, we should do it.
