Halloween is not catholic stuff. In Brazil as a child, I did not even know it existed. It has nothing to do with All Saints' day.

Only as a teenager reading Peanuts I learned from Charlie Brown that in USA there was some kind of witch-festival with candies.

HW is anglo-german stuff. "Witch culture" is stronger on protestant lands, because superstitions and accusations could grown into mass histeria (Salem, etc). I remember being amazed how americans could be so primitive as to be witch-hunting in the 1690's. If some woman were accused of witchcraft in catholic lands the church would investigate with strong cepticism, and calumny was a grave crime everywhere.

witches flying in brooms were not in our imagination until we got american cartoons, much less salem-level stuff.

That said... we repeat the pagan god's names when we name weekdays. We learn mithology, read Homer, docs use esculapius rod, etc.

if nobody takes the witch-pagan stuff seriously... why HW would be different? We lose so much time idolizing sportsmen or Batman, why not witches or ghosts?

'wrong' is when real satanists exploit it to their ends.

or when HW occupies so much mental time that people forget All Saints Day, or All Souls Day.

But halloween is not the only secular feast pushing religious ones out of our minds, every decade there is another woke-festival worse that the previous one.
