I really, really love this movie! Did you know that Halloween is on the rise in Asia?

No, we didn't know that!
Here in Italy, Halloween is definitely NOT on the rise

I am very sorry to hear this. I am no expert, but isn`t Halloween originally Catholic in nature? I am surprised that it is not more popular in the heartland of Roman Catholicism. Why do you think is Halloween not so popular in beautiful Italy? I have seen that it is on the rise in Switzerland, which is a neighboring country of yours.

Halloween is not Catholic! It is originated from ancient Celtic harvest festivals, particularly the Gaelic festival Samhain. A lot of Catholic priests here in Italy hate Halloween and that's pretty sad

This is incorrect. Although this is largely spread through the media in the West, Halloween is actually rooted in Christianity, not in any particular form of indigenous Celtic religion. The historical evidence is actually pretty straightforward:

(I am a historian, so I simply had to give you these sources. I hope that they are useful for you.)

Well, we didn't know that! Thank you!
But this doesn't change (sadly) the fact that all priests here think that this is a pagan (or worse, a satanic) ritual festivity, so a lot of people don' celebrate it

This surprises me. Don't they know their own history? This is quite shocking.

The history of the Christianity is stained with blood, so maybe they prefer not to know what the church did in the past XD

"The history of the Christianity is stained with blood."

Whose history is not bloodsoaked? One just has to look into how many people "peaceful" democracies have killed in the 20th Century.

Halloween is not Pagan, my dude. The Holy Roman Imperials celebrated a similar feast ("Allerheiligen") ages before the term "Halloween" was even coined. The idea that Halloween is Pagan is a 20th Century myth. Take a look at this book:

https://books.google.de/books?id=VBRRAAAAcAAJ&pg=PP1&dq=Allerheiligen&hl=de&sa=X&ved=0ahUKEwiw87XpoJ7lAhUIb1AKHQywABcQ6AEIOTAC#v=onepage&q=Allerheiligen&f=false

Please note the similarities between modern day Halloween and Allerheiligen: people dress up and walk through the streets to knock at doors to ask for food. Carved pumpkins are used as decoration and the people go the mass at midnight. Does this sound familiar?

The "Reichskirche" ("Imperial Church" the term refers to the Roman Catholic Church) organized the day. Please note that the Bishop himself is himself a fan of the feast. It does strike me that your Roman Catholics have forgotten their own history, because it was the "Imperial Church" which not only allowed and celebrated Halloween, but largely propagated it in Roman Catholic regions. Please note that the objections come from the Protestants who call the feast "Heidnisch wie die ganze verfluchte, papistische Kirche" ("Pagan like the whole cursed papal church"). It may be possible that the idea that Halloween is Pagan originally stems from the anti-Catholic propaganda. Either way, there is zero evidence that Halloween comes from G
Paganism but excellent evidence that it is a Roman Catholic feast.

Thank you for educating us about this!

You are welcome, friend.

"Allerheiligen" literally translates into "All Hallows' Eve" by the way.
