In the old curriculum pupils would learn select things about the main religions. However, that has been largely thrown out as it causes too many problems. It has left the new curriculum bland and lacking substance, so I can't see religious education limping along for much longer outside of GCSE, a level.
In certain schools in England, for example church of England schools, children are exposed to Christian ideology. I hope in time this will die out, as it's not really a choice of your only local primary is c of e.
But tbh, no they're not enduring Christianity in the same way as gender ideology, even in church of England schools. Even when I went to one in the nineties, I was allowed to be a non beliver and attend. Kids are not threatened with re-education of they don't agree Christ saved us all or bow their heads in prayer. As long as kids remain respectful, tolerance is shown.
I mean old fashioned tolerance being the natural type, not the forced activist type.
