Sorry to answer so late (it's been crazy in my house) but it's all PC to me. Can't offend anyone.

No Halloween but harvest party. No Christmas but winter festival. No Easter but spring fling. The only holidays our schools recognize is Thanksgiving, Labor Day, Memorial Day and those type.
Now it's up to each teacher if they want to decorate their classroom with ANY holiday and if any parents want to send in holiday treats that's okay. I sent in for my daughter's class Halloween goodie bags with candy, stickers, and plastic bug toys in them.
