OP here. Thank you, some really useful and understanding thoughts here amongst the customary tiresome responses to my Christianity. As I said, I naively thought that for once MN it might be possible to be Christian without the slagging but so much for that.
OK, some direct responses. First, thank you Missymoo x Your post about all the African etc stuff describes the really extreme end of why I have reservations about witchcraft. I'm sorry, I've been socially conditioned to find that all that stuff worrying. I don't think that it's the same as the apparently good-hearted pagan belief system around our connection to the earth. That seems to be just a difference of faith and doctrine, much like the distinction between me and a Sikh or a Muslim. Part of my difficulty is not knowin where the separations between the various beliefs and practices on display at Pagan Pride are, so I take all your points about reading and getting a bit more clued up.
Let me be absolutely clear about the fact that I do not think all other religions beside Christianity are evil, mumbo-jumbo etc. On the contrary actually, which is why I'm struggling with my own feelings about this. I categorically do not think pagans, wiccans etc are deviants, child molesters or whatever.
Greenglassteacup: good question, thank you. The former, I'm pretty sure.
A bit of further context here, lest ye think I am ramming my faith down her neck (I don't think even she would see it like that). Anyway, as I said she's the eldest of 3. Middle child does identify quite strongly with family's Christian ethos, and finds eldest's constant talk about her new beliefs a bit upsetting. I have to referee that. Youngest is open to both but is very up for being convinced that a religion with pretty things like crystals and lovely earthy gods is much more fun that dull old church.
Most significantly, a detail about the main dd here that probably was a bit lost in my OP. She is autistic, thus, any interest, idea, belief etc is taken up full time and with great passion. So, this is pretty much the only thing on her mind. It's the summer hols obvs, so most of the other distractions of life are not available. However, she does see friends and because of the keen[n?]ess of her interest, talks constantly to them about it too. As her parent, that is something I may be held accountable for by theirs. Interestingly, none were available to accept her invitation to go to PP.
The main thing about her ASD is that she talks about this all the time to whoever will listen. And when I say "talk to", I mean it literally. There is not much 2-way conversation, except that all speeches finish with the question, "so what do you think, mum?" or "what do you think of my runes, mum?" or "why would you have a problem with me getting a cauldron, mum?".
The fact that I don't just trill "oh, I think that's lovely sweetie" doesn't make me a fundamentalist, I don't think, so shoot me. What do I think? I think it gives me a tight feeling in my tummy and, knowing my daughter and how things go with her, as a Christian mother in the context of a family with a range of views I'm not sure what to say - because I'm trying to balance my desire to respect her views whilst being true to my own, and giving her the moral direction I think is my job.......
...... Which is why I started this thread, in the hope of getting some good and well-meant advice, so really sincere thank you to everyone that has tried to give some. I know loads of you are atheists and think I shouldn't want my children to grow up with the same views and beliefs as me, but if you have religious faith of any sort, it kind of goes with the territory.
