Halloween has gotten out of hand

When I was a child Halloween was for kids. Now it has decayed into something very low and nasty. When Rocky and I stepped out of church after Mass I saw four adults in Haloween costumes. One was a vampire and one was dressed as a prostitute and one was a cowboy. I'm not sure what the last one was because I looked away before I got a good look at him.  They were loud but looked away when parishioners glanced at them. When the church bells rang the Halloween revelers began wildly rocking back and forth toward the ground. I assume it was some sort of mockery of holy things  but as we hurried into our car I  wondered why these people felt the need to come to a Catholic church.
