I agree. Your case is very legitimate! I don't have anything against Wicca per se, and I am not a "religeous" person at all. My D24 is "wiccan" (she's always danced to her own drummer ( ). But, I still think your argument is a valid one and you should protect your D.
I didn't really have anything against Wicca either, until fairly recently!! But I asked her myself, in an email back at the beginning of all this, to back off so we could work on our marriage. And she wrote back, quoting some Wiccan "rede" and spewing a bunch of new-age nonsense about supporting our whole family and where to serve in this space--and hence, refusing to "withdraw from the relationship." Because it would be untrue to the goal she has set for her life--apparently to be a homewrecker--and using some Wicca stuff to justify all of this. So I'm finding myself just a little less tolerant these days!
