To elaborate, religious pluralism is generally taken to mean one of the following things:
1. The existence of several religions living more or less in peace. This does not make any statement about the nature of religious belief, just an acknowledgement that a lot of people have a lot of different ones. When we speak of the United States as a religiously pluralistic society, this is what we mean.
2. The belief that all (or at least most) religions provide a valid path to the Godhead. This is more iffy, since anyone who believes in hir religion in a literal sense is likely to dismiss all other religions as false due to their mutual exclusivity. Still, the advocates of religious pluralism, myself among them, generally see an understanding of the validity of all religions as crucial to ending the prejudice and bigotry that religion has caused. Religious pluralism is gaining increasing adherents within theologic circles.
