Should Church members celebrate Halloween?

THERE are some members of The Church of Jesus Christ of Latter-day saints who DO NOT believe in celebrating Halloween, mostly because of its dark beginnings. That is their freedom of choice to do so.
When I grew up in the 1950s and 1960s, Halloween was mostly about scary and the equivalent in costumes.
However, today that is NOT the universal case. When some 170 children came to my door on Halloween night of 2019, I'd estimate that 95 percent-plus were wearing super-hero and fantasy costumes -- not scary ones.
Halloween today is mostly about candy and cute or inventive costumes. Yes, there are some haunted houses one can visit and even Lagoon Park in Farmington, Utah, hosts "Frightmares" each fall, with a scary twist.
However, even some of the most popular decorations of Christmas have strong roots in pagan rituals and so does one forsake Christmas because of that shady past?
The choice is yours, but about the only advice on Halloween in Church Handbooks has been that masks are not allowed inside a Church building.
So, Halloween is what you make it.
