If you follow a religion.
Would you make your children follow that religion even if they didnt want to???
But if you didnt follow a religion and your children wanted to go to Sunday school or church Would you let them or just say an outright NO??
If I followed a religion (and was still the same person that I am), I would probably want my children to at least attend enough of my religion's services/classes to get the basics.
I do not, however, follow a religion (anymore)... so, what I do and have done with my children is to allow them to go to attend and/or worship any religion/god that they choose.
I have strongly suggested (and pushed as hard as I could) that they: 1) study all religions, so that they can objectively decide what they really believe, 2) specifically research any particular religion/religious sect that they like, as they should be prepared for whenever they are confronted by a cult, and 3) study science.
My children have followed my guidance and studied comparative theology from both a historical and theological perspective. They seem very grounded. They have gone with friends to religious services of a number of different religions and (as far as I can tell) are intelligent and tolerant of peoples of all faiths.
They seem to frown on ignorance and intolerance, and laugh at cultists.... which makes me happy.
