That's because the world is full of sin friend. I'm not suggesting you didn't know that, just pointing it out.
christmas (I decapitalize it on purpose, because God hates abominations like this) easter, santa, tooth fairy, all kinds of other things... they all have pagan backgrounds, secret evil meanings... you name it. They're full of sin. God also tells us to not keep our own traditions or do as the pagans OR take/add to the Bible. Yet all those holidays do 1 or all of those.
I know what you mean though, it's hurting these kids. I pray for them, and the generation of teenagers every year. With sin everywhere, it's more difficult now for our youth of today to see the Lord. God love and be with us in these times!
Love forever. =)
