I think it is only a problem because of the superficial nature of religious dialogue - especially such as happens on internet forums - we take the label as defining the person and their beliefs...the reality is that there are many nuances and shades of meaning and understanding in each believers conceptions...and in the case of some traditions, we really don't know for sure what the founders really taught - we have to interpret the tradition as best we can in our own circumstances. I prefer (these days) not to take a label at all - if I did, one day I'd be a pantheist, the next a humanist or a universalist...the "light of religion", I think, is seen best by looking at as many as we can and taking the best from each - but who decides which bits are "best"? We can each only do that for ourselves - and if what resonates with us most resembles an existing religious tradition, I guess there's nothing wrong with taking that label...OTOH - I am reminded of the thought in Isaiah 4:1...so I guess I should say there's nothing wrong with taking such labels as long as the intent is not to deceive.
