First of all. Thanks for the insight. It doesn't change my perspective of this holiday being creepy, but I guess for some people they can consider my perspective of this holiday as a compliment in a way. I have my reasons for why I find such a holiday like this creepy, but I don't think it would be fitting to discuss my reasons here since it's too controversial, people reading the short version of my reasons would badly misinterpret it, and in hindsight would definitely be a topic under Debate Pit which I might consider doing (if I feel like it).
As for Halloween being equivalent to the Celtic Pagan Tradition of Samhain I don't know if that holds true though since there are some sources that says otherwise about the Present Halloween not being equivalent to Samhain. I guess Samhain could be considered as the origin of Present Halloween though in some ways, but both Traditions do their own thing in the end. Maybe you can elaborate further about this matter?
The part I found really interesting in your comment that I bolded out for convenience is the notion of people dressing up as monsters to be unrecognizable to bad spirits. While I appreciate your sentiment to share your religious viewpoint about this matter, IDK if what you say would work well under my case. Since I abide under my own religious viewpoint, I fight my evil spirits instead of hiding away from them. I find it very unjust that just because my ancestor did something bad for a witch or a wizard or an evil spirit to lay a curse upon them doesn't mean that I as my ancestor's descendant have to suffer the same curse as them. Descendants are usually not like their Ancestors every now and then. Hence, I stand for myself and fight them off until the curse is no more.
I purify myself on a daily basis through self-reflection, acknowledge my faults, take great shame at them, and fix myself while making sure I am and do not come across as a sanctimonious, hypocritical, holier-than-art-thou, self-righteous prick. If I am a sanctimonious, hypocritical, holier-than-art-thou self righteous prick, then I shouldn't have any reason to self-reflect in the first place since I would believe that I have no flaws and thus am morally superior to everyone when I clearly do have flaws like any other Human Being.That way I'll fight off the evil spirits and be a constant annoyance to them so much that they would be driven to insanity and immediately run away from me.
Bottom line based on my personal experience, is that evil spirits don't know when to give up and get stronger, so judging by this tradition to dress up as monsters in order to be unrecognizable to bad spirits, IDK if that works. Wouldn't spirits generally have the ability to look through a person's monster disguise regardless of them being good or bad? It's a puzzling question indeed when talking about the notion of spirits that most people nowadays don't believe spirits exist for granted.
Because the bottom line is that I believe in spirits and abide on my beliefs to fight the evil spirits off and get stronger than them till the day I die.
Thanks for the history and spiritual discussion behind Halloween. I appreciate it. I apologize if I hurt you in anyway. That's not my intention, but whatever floats your boat.
