Why I do not believe in Halloween?!

So Today we were wandering down the asile at Fred Meyers and remind you it's about a month outside of halloween and so of course Freddies have their halloween stuff out. I really don't see the point of halloween and it's not because I can't go trick or treating. It's just to me that it's the devil way of being able to walk among us for the day and spear hate and fear. I am just in total shock that I feel this way. Thinking that one day soon I will be a mom to my own children and let allow it's something that I don't believe in. How do I explain this to people on why I don't feel that my children should take part in this? Being a christian is very important and not spearding the way of the demon or the devil is very important to me not to do!
