Why don't religions kick the hell out of each other (figuratively)?

I'm baffled as to why there seems to be such a dearth, or even total absence, of sound, intellectual, public debate between religions, despite each of them claiming that it and it alone uniquely possesses the 'absolute truth'. All their common fire seems to be directed at those who do not believe in any omniscient, omnipotent, benevolent Creator, rather than aiming at those believing in a Supreme Being at complete odds to their own belief - though Paganism does actually sometimes attract censure too. (On the grounds of worshiping 'false gods?)

I feel intensely irritated that whenever the question comes anywhere close to going asked, the topic is always closed down by a statement of the analogy "Ah, but you see, there is more than one path which leads up to the summit of a mountain." (or similar words), and this platitude is then left as being a satisfactory response. Well, as no one else will probe deeper, I shall.

So, presumably, what is meant is that there is more than just one way of reaching Heaven/Paradise/Nirvana, or what you will - and, further, I suppose, it's irrelevant which path you take as long as you finally reach the 'peak'. Is that really what they mean?
Let's ask a few questions:-

Does a Protestant Evangelical Minister really believe that it doesn't matter if you think that the Pope is God's sole representative on earth?

Does a Rabbi think it unimportant if someone refutes that the Jews are 'God's chosen people' and publicly states that anyone believing in a 'Second Coming' of the Messiah' is deluded?

Is an Imam unconcerned if one of his congregation converts from Islam to Christianity, thereby rejecting the belief that the Archangel Gabriel ever appeared to Mohammed? (Btw the single greatest 'crime' in Islam is apostasy.)

Is it of no consequence to the Roman Catholic hierarchy if the Virgin Birth is denied? - as well as the Immaculate Conception of the Virgin Mary and the Assumption into Heaven of Mary, body and soul - the latter two being the subject of infallible Papal pronouncements ex cathedra and therefore 'beyond dispute as fact'. Likewise are they not bothered that Muslims don't believe that Jesus Christ rose from the dead - or, as some believe, was even crucified at all?

Does a Mormon hold that someone's religion is irrelevant? I heard only yesterday that in their (grotesque?) post-death 'baptisms' of anyone in the past whom they wish to 'enrol' to their faith, they now claim that Anne Frank, of all people, is now a Mormon!

Don't other religions really mind that the reincarnation doctrines of Buddhism and Hinduism are in direct contradiction with their own 'one chance in one lifetime' beliefs?


I could go on and on but it's more than a little curious that religions seem so reluctant to disagree with each other publicly when I should have thought that it would have been the core of intellectual debate. It's almost as though there was an unwritten agreement not to diss each other but to focus their attacks on those whose reason casts doubt on the existence of any Supreme Deity.
Of course no one ( at least no rational being) would like to see a return to inter-religious wars, crusades and slaughter which have pervaded history, though, as we all know, there are regretfully still parts of the world where exactly this is advocated and, indeed, practiced. But, as I say above, it's strange that they seem to get most excited by those of us who don't subscribe to any of their faiths. It's like one is required to believe in some god - but it doesn't really matter what sort of god that is. (I think many betray their ignorance of Buddhism in particular, which does not hold to there being any individual Creator-Deity) .

So turn your cannons round, all you religious people. Be fair and also attack ALL those who think that your own particular beliefs are absurd and simply false.

Meanwhile, as long as the current situation prevails, it's all very peculiar - and exasperating.
