I do have to chime in on this topic because I am one of those people who adores celebrating Halloween.
We are renting a townhome, and I put up a door cover, spider webs, and some homemade mummy lights - along with some ghosties on our garage door and some light up spiders in the windows. On Halloween night, I had a small haunted house in our one car garage, and participation was optional for the neighborhood kids. I was dressed up and handing out witch's finger cookies to the parents and candy to the kids - regardless of whether or not they went into the haunted house.
Most of the kids LOVED it. But I had one parent who had an issue with me - she came up to me with her two youngish kids (I'm thinking 5 and maybe 7) and was P/A about the decorations. My next door neighbor was out front with me, and we were chatting and my next door neighbor mentioned how fun it was that I was so into Halloween and the kids were getting a big kick out of it... when ParentMom chimed in and said, "Well, we live in the townhome behind this one and we were forced to watch it get put up. Good thing my kids are OK with this."
I didn't have any bloody heads/body parts/what have you on display, and honestly, spider webs and ghosties are too much?
I just smiled and turned away 'cause I had no reply.
