And, don't worry so much about razor blades or drugs in your candy. During the past 100 years, very few such incidents have happened, and more happened at home than by picking up tainted candy. They hype that up so much these days. Yes, there is always that chance of picking up something bad--about 100 or fewer legitimate incidents in 100 years. Just go out and have fun--the greater danger is getting hit by a car while trick or treating.
Even if you don't go out, it never hurts to hand out treats (obviously, I do not condone those few scumbags that do hand out poison or razor blades with their treats. Those filth belong in jail, for a good long time.) Get a few strings of Halloween LED lights and place them, or place a LED candle in a pumpkin (real or fake--the fake ones are reusable). And do you really need those hideous items? I find such things as bats, ghosts, witches, spiders, and the like to be just fine without fake crime scenes.
Ditto for Christmas. It is true that it follows the pagan sun worship festival (the sun "dies on the cross" three days before Christmas, then rises off the cross on Christmas Day). But that doesn't stop anyone from having fun that day. Be mindful to spend within your means, and that it is not the end of the world to have some fun that day. Whether or not you go to church is up to you. The only thing I ask is that you refrain from drinking and driving--which can get you in the hospital or jail for the holidays, giving you a dreary Christmas instead of a merry one.
