This is not logical or Catholic. Logically, there can be, at most, only one true faith. All other faiths must be false to the extent they differ from that one true faith. It is the place of a Catholic to faithfully represent what the Church teaches, namely, that the Catholic religion is the one true faith and that its genuine teaching does not err.
Indeed: I’m not quite sure what is it that you disagree on here? We can all, as I said, defend and promote what we believe. Faithfully and firmly. HOW we do this is important, however, and must remain in keeping with the (quintessentially Catholic) principles of respect, compassion and humility, as well as an awareness that others who may be doing likewise in promoting their own beliefs, are from their own perspective also promoting truth. This doesn’t mean ‘accept that their version of Truth is equally valid’. It means ‘show some respect, and don’t forget they’re trying to do what’s right from their own viewpoint, just as you are’ - and remembering we’re allultimately human and may be subject to error in our understanding and interpretation of God’s revelations or will.
Passing judgement, however (as opposed to promoting what we believe to be Truth) is neither your business nor mine (’judge not, lest ye be judged?’), and in my own experience, I’ve found that others tend te be more receptive to Truth when it’s presented clearly and humbly from that perspective.
