There are several takes on this, depending on who you talk to. Some see it as totally necessary in order for the planet to get along. Others are more, 'You do your thing, I'll do my thing. If you don't bother me, I won't bother you.' and leave it at that. Some also say they benefit from incorporating, amalgamating, using several religions, and others like to just sit back and enjoy the diversity. I think at many actual real life interfaith forums, you'll find a Hindu or two there representing us. Of course that individual has a hard time representing all of us.
