The first time I encountered this was at Uni when a girl I was friends with refused to partake in any Halloween celebrations whatsoever on the grounds that it was "evil". Her family were evangelical Christian, and even though she was more relaxed in her religious beliefs than them she wouldn't budge on Halloween. It was a shame as she missed out on all of the fun. But she'd never celebrated it, and her family would go out on the 31st to avoid trick or treaters.
I don't understand it? My mum was raised a Christian and has always loved halloween. She sees it for what it is, a bit of fun for kids.
I feel a bit sorry that these people won't allow their children to take part in the same customs that their peers do. Doesn't it leave them feeling a bit left out at school etc?
Should these people just get a grip and stop being intolerant?
