The Pagan roots of things in our culture and our language are all around us and don't mean anything unless we choose to let them. Relax, Halloween is all about a bit of fun, just like Harry Potter.
Douglas can speak for himself, but it is not the roots, that bother me, it is the fruit of the roots.
The way Halloween is currently celebrated promotes superstition and celebrates indifference to true religion. In a cultural vacuum it is probably defencible, like the Nazis celebrating German folk mythology. In the context of today's culture, it is deplorable. Just like Harry Potter, or Nazi goosstepping in Berlin.
I don't. I observe the same holy days that Jesus Christ observed. They're listed in Leviticus 23.
