When a colonizing religion moves into an area it is inevitably shaped by the natives. It usually turns into a hybrid version of the colonized and colonizers religion. Sometimes, to the point that it creates something altogether unique
Evangelical Christianity has some dirty words. Words like Liberalism, universalism and pluralism are used to restrict the deconstruction-reconstruction cycle. We use these words as boogey-men so that we can quickly write off anyone associated with them (farewell, Rob Bell!). They discourage spiritual growth by clearly demarcating the boundaries of "orthodoxy". I'm sure other faith traditions have their own versions of this, too.
But, these ideas aren't that bad.
Google tells me that pluralism means a number of similar but distinct things:
First, it defines pluralism as:
a condition or system in which two or more states, groups, principles, sources of authority, etc., coexist.
And then it gives some examples:
a form of society in which the members of minority groups maintain their independent cultural traditions.
That fits us, we're all about maintaining cultural traditions. In the end we're more of a mosaic than a melting pot, more pluralists than perennialist. Google continues:
a political theory or system of power-sharing among a number of political parties.
a theory or system of devolution and autonomy for individual bodies in preference to monolithic state control.
We support political diversity and avoid identity politics. We are libertarians when a system of equality can be supported by such.
And finally, pluralism as a philosophical idea:
a theory or system that recognizes more than one ultimate principle.
Ah, this is at the heart of it all. We recognize that there is probably more than one ultimate ideal. If there isn't then we certainly can't properly articulate that ideal by ourselves, within our own tradition's echo chamber.
The Pluralists recognizing the importance of living according to these principles.
