@Nullo – I agree with @Jabe73. It’s not true that all forms of religion say that they represent the only one true faith. An example is my own faith (Liberal, Protestant Christianity in Germany). Another example is Hans Kueng’s form of Catholicism (which differs from the one promoted by the Vatican). The following text is worth reading and the approach doesn’t mean that all faiths are equal, but it means that none of them can claim to be the only true faith:

Here are some key messages:
“We condemn aggression and hatred in the name of religion. We affirm that a common set of core values is found in the teachings of the religions, and that these form the basis of a global ethic. We affirm that this truth is already known, but yet to be lived in heart and action.
We do not consider ourselves better than other women and men, but we trust that the ancient wisdom of our religions can point the way for the future. By a global ethic we do not mean a global ideology or a single unified religion beyond all existing religions, and certainly not the domination of one religion over all others. By a global ethic we mean a fundamental consensus on binding values, irrevocable standards, and personal attitudes.
The spiritual powers of the religions can offer a fundamental sense of trust, a ground of meaning, ultimate standards, and a spiritual home. Of course religions are credible only when they eliminate those conflicts which spring from the religions themselves, dismantling mutual arrogance, mistrust, prejudice, and even hostile images, and thus demonstrate respect for the traditions, holy places, feasts, and rituals of people who believe differently.
For representatives of religion who stir up prejudice, hatred, and enmity towards those of different belief, or even incite or legitimize religious wars, they deserve the condemnation of humankind and the loss of their adherents.”
