Xeno- is a prefix, from a Greek word meaning alien, stranger, or guest. We find it in words like xenophobia, fear or hatred of the foreign, and xenomania, love for the foreign. (In Paganism, I think we can see bits of both of those!)
I hope that we don’t practice xenolasia, the ancient Spartan tradition of excluding strangers (or making them obtain special permissions) – on the contrary, I hope we have a (metaphorical) xenodochium, a room for welcoming unknown guests. I know that there is quite a lot of xenogamy, cross-fertilisation, happening, and I’m sure that in the eyes of many we, as a community, as xenomorphic, having a strange or unusual shape.
