Of course we think our way of seeing things is "better" or else we wouldn't hold them as true. But "better" is again, relative. It's relative to the context we find ourselves in on many levels. Something which today serves us better than what we believed previously when we were younger for instance, actually would not have been better back then. We didn't have the necessary prerequisite contexts in order for that 'higher truth' to make sense, and hence be useful to us. So better is not only cultural, it's developmental as well.
That said however, higher truths are always higher truths, regardless of whether the person can fathom them or not. It's like saying being 30 is older than 15. It always follows suit after 15, and cannot be accessed by skipping over 15. 15 is transcended, and included in being 30.
The same thing with higher perceptions of truth. They are built upon the lower perceptions, like climbing stairs you are transcending them and including them in higher realizations and higher levels of awareness. Generally speaking, these higher levels are always experienced as better by virtue of the the level of inclusiveness they hold and what they afford the individual, or the group. But again, the value of them can only be realized once one is at that stage developmentally.
So, the more accurate way to express this would be to say, "I can see how you can see that, given for where you are at. I however don't see those things in those terms for where I am at." That is easier to say of course for someone who had previously thought in those terms but have taken the climb up to the next stair or three or five.
However, the person on the stairs before those higher stairs would not be able to say that, because they don't have the necessary context yet to see what that other person is seeing, to perceive as that other person on the higher step perceives from that altitude. Since they have no experience seeing and thinking like that, they cannot relate to it in themselves, and assume that person in what they report is just crazy or something, somehow not yet as "smart" as them, lost, blind, confused, and so forth. This is pretty typical.
So context is everything. Content (truth) is relative to context (the depth, width, and height of the container for truth). They are nested bowls of Truth, containing the various objects of truth that can be held at that given level, or container, or context.
This by the way, is a nested hierarchy of containers within containers within containers. The larger containers hold the smaller containers within themselves, and each larger container or context is able to hold more and more objects of truth, all the previous truth, and new truths the smaller bowls cannot contain.
With this much more content available in the larger vessels, what truths were understood from exclusively within the smaller containers becomes understood in a vastly larger and more inclusive context. So all told, all truths are not equal.
But one must be careful not to assume that how they are currently seeing a truth, will not at some point be seen to be less adequate, and a better, higher, more inclusive truth be realized.
I think everyone at every level should practice that humility. Hence why I say, to try to prove another religion as "wrong" lacks such humility.
That can be true in the context I was speaking above, but that's not true necessarily in all cases. You can obviously have people all on the same level, the same staircase altitude, all arguing with each other what they are seeing at that altitude together. That has less to do with higher states of awareness, then it has to do with interpretations of things at that given level. That's all part of the process.
But to the point about arguing other religions are "wrong", that's like saying floral patterns on furniture are wrong. It indicates the person who assumes other practices and beliefs of religion at that particular given level that don't look like themselves must be doing it wrong, not recognizing basic differences that are allowed to exist. You can have a leather chair, a wooden chair, a cloth chair, etc. Not recognizing that they are all used to sit upon.
