Welcome to the community @TracyR
Australia accommodates a diverse range of cultures and beliefs. Evident from other nations, when one part of the community insists on changing all others to the one way things begin to fall apart.
There are those in the community all for spending on an American style fun time on a school night. It’s a free choice and one I might tolerate providing I don’t need to join in.
There are those who see little value, or might prefer a different approach. Happy to celebrate the changing of the orbital cycles. Especially the about turn off the lengths of the days in winter.
P.S.
I don’t need Halloween. We’ve an Ancestry subscription.
