I am a pagan. There are pretty much no widely accepted texts within paganism that make any statements about subject. In my experience most pagans are quite happy to coexist with other religions in general - and given that in almost all circumstances pagans will be in a small minority that makes perfect sense. On the other hand, most pagans that I know are far less happy to coexist with the more bigoted and hateful varieties of religion.

There is a strong feminist trend within paganism and this - particularly linked with the ahistorial but often assumed heritage of witchcraft, and the associated history of hanging and burning of witches - does not lead the more patriarchal end of the Abrahamic religions to sit well with a lot of pagans - and I know a lot who are far happier about visiting the roofless moss-covered shell of an abandoned church, with a hawthorn growing in the apse than they are visiting an occupied one (unless it is in search of a sheel-na-gig etc).

On the other hand, there is a strand of Norse paganism that crosses into white supremacy and neo-nazism, so that brings its own hate, bigotry and patriarchy. I do not know what their stance on other religions is.
