Hallow'een isn't an American holiday - the rest of the UK have been celebrating it all along and know very little about Guy Fawkes! I suspect England celebrated it before Guy Fawkes took precedence at around the same time.
Perhaps one is a historical event and one is a cultural entity that's been in place for a very long time (since the dark ages) and all historical events fade over time where embedded cultures and beliefs don't. But it's too simplistic to blame the Americans when we celts are equally to blame!
I have no recollection of ever celebrating Halloween when I was a real young'un in the early '60's - but i do remember doing 'penny for the guy' for many years - so although I accept that Halloween was a pre-American pagan celebration, I still think it has become synonymous with America...and don't get me started on the craze for American style 'baby-showers' nowadays!
and we do now use pumpkins cos they're less smelly than turnips, frankly. And I can make soup with them....)
We don't do penny for a guy (burning Roman Catholics is not really very PC) but we have bonfire night every year with a cake, toffee apples, stew etc Its not changed much since I was a kid.
In this part of Ireland the Bealtaine bonefire to mark the Celtic season of Summer starting (1st May) is a big thing, it never died out here.
Some sort of alien influence.the coconuts. Why? Why? In Ireland. At Hallow'een
Some sort of alien influence.
Even as a child it puzzled me. Hazelnuts are at least a traditional Irish thing, though peanuts are as mad as Coconuts. They are not even nuts!
