I actually think it's pretty awesome that so many of us like different things. Personally, I don't go in for the gore or zombie babies either, but if someone else loves that stuff & it encourages them to decorate? Sure! Have at it! I don't at all like torture scenes & clown stuff makes me run in fear, but some people are willing to pay money to have clowns chase after them, and that's okay. Crazy, but okay. LOL!
I love the bone skeletons like the birds, spiders, rats & scorpions, even though I know they aren't anatomically correct. But I'll never own a cat skeleton because they actually make me feel a little sad, which I know might be weird. I have two beloved cats who are buried in my back garden though, so it just doesn't feel right to me to have one as a Halloween decoration. But of course they are on the shelves along with the other boney creatures. I just choose not to buy it.
Having a Satan prop on display doesn't feel wrong to me, but I know some people who would think that was a serious problem. Do I think that some décor is offensive? Yes, I do. I think there are some things that are better kept privately in your home if you like it, rather than displayed in your yard. Part of my mindset comes from having small children - I don't really think they need to see some stuff. I know that you can't please everybody all the time though, but I personally think it's a good idea to think about your audience.
To me, Halloween is a community event. I'm inviting people into my yard as guests, and I want to treat them as such. So I want them to have a good time & feel happy that they came to see us because we made their night better. Not cry or feel sad or disgusted. But you know, every year we get kids crying because even though we try not to be TOO scary, you never know just what's going to set them off.
I guess my long-winded point is to say is that we all add our own bit of Halloween, and I'd rather see a large variety of props available rather than a limited amount, even if some of them aren't to my taste.
