I live in a very diverse area. This year and last I've noticed a huge increase in my white hippie mum mates attending Eid al Fitr (end of the Eid fasting) celebrations. Down the road from us they get big tables out and shut the road off, it looks a great street party!
My issue is that we (Non Muslims) haven't partaken in Ramadan so why should we get to celebrate the feast bit? If we were really into celebrating every cultural occasion then wouldn't we do the fasting bit as well?
I can't think of an equivalent for another faith joining in on our festivities without doing the religious bit first. Most people eat Easter eggs without having given anything up for lent. Most people nowadays just enjoy the present and food bit of Christmas without thinking too much about Jesus being born.
Am I just being grumpy? I think if I was Muslim I would find non Muslims just joining in the feast bit kind of strange.
