We don't "celebrate". Our church has "candy night" where the children 6th grade and under can walk the gymnasium and receive candy from the parents so that they have a candy holiday but no costumes or the like. We go shopping for Christmas on Halloween - the stores are empty!
Its not the same as when us middle agers were kids and it just isn't safe or appropriate IMHO.
Eeewww
You're right. . .it's changed a WHOLE lot.
