In exploring the net, one comes across a lot of slights against this group or that one. Some people struggle to understand those who only work within one culture, others struggle with the idea of dealing with more than one culture. Some are even on the warpath at times to prove just how wrong everyone else is for doing what they don't do.
I have been fairly eclectic in my experiences on my path, and as such I usually get to hear about the "horrors" of "cafeteria style paganism." (fyi, I am not a Wiccan, I am a Witch and a Mystic.)
But not all eclectics are operating from that kind of perspective. Some of us practice what is called Responsible Eclecticism.
This is a lot of work - you have to research not just the rites, but parse out precisely what the point of this ritual or symbol was in all its glory, and dissect whether that will apply viably to your path. Responsible Eclecticism does not go about lifting things because of whims, nor is it based on a lack of meaning in the path.
When multiple cultures interact, there is always a certain amount of blending, and responsible eclectics choose to be cautious and considerate with how their own beliefs blend with others. They do their best not to steal from extant cultures, and try to walk a balanced road between reconstruction, invention and UPG (Unverified Personal Gnosis). It's hard.
Most of us don't want to be looked at as being in the same class as those who try to progress aimlessly.
And some of us are not in this position by choice - some of us were tagged by Gods who have origins in differing nations/cultures/etc, and when called by someone like that, what can you do, but learn a bit and commune to see if its the right way to go.
Thanks to all, and Blessings.
