I would opt for other kid classes. I know that can be an issue though if it is school based.Even scouts can be an issue if it is made up of kids that go to the same school. I would skip the homeschool group if my dd had to take the *girls* class.I am sure there is useful things taught,but I would want my dd to be able to take the wood calss too. Building is a useful skill for all!
I don't think I would want my kids taking the creation class.Yea,they could sit in and hear it,but then the others would disrespect them for not believing.Shoot,my ds got harrassed by classmates for not believing in Santa,so I can imagine when talk turns to *god* beliefs.
Hopefully your neighbors will be OK,but I doubt it with the go to church/save the soul.I am sure they will take every chance to bring up religion.What a shame that kids just can't play,and the adults just relax,chat,and eat some good home cooking! I just don't understand why people can not accept each other.
If there was nothing around useful for the kids then I guess we would be left with being each others support,staying home most times,and using the computer/internet for a social outlet. I might even consider moving if people were very negative towards me and the kids.
I hope you find something that works!
