Bloody hell, I hope it doesn't get that bad here in Oz. We do have some radical groups who want to stop kids from having easter hat parades and christmas plays at school.
Personally, I don't care what religion you are, if it is a holy day for you, then it's a holy day, and you should be free to celebrate it in what ever traditional manner is appropriate.
Obviously there have to be some boundries set so that the general good and well being of the community is not put at risk, but in general terms I have no problems with any religion celebrating it's holy days.
