The holiday that showed up because of it being the day before All Saint’s Day isn’t religious?
The holiday about spooky things and kids dressing up and getting candy is not religiously exclusionary no. Christmas’ origins were not, either, but we’re not talking about the origins of these holidays, we’re discussing them in their current form, so go be a pedant on some other thread. I’m sure there’s plenty where the pedantry could actually be relevant to the conversation taking place.
It sounds more like you’re just looking for reasons why your capitalist holiday is somehow more pickme acceptable than the other capitalist holiday.
You’re not quirky and unique because you like candy more than presents.
