If you want to call this lying to a child, thats more than extreme point of view. Somehow I do not think Jesus will be too angry about the Easter Bunny or Santa Claus, hanging a stocking or, coloring eggs, or putting out the Easter Basket. I'd rather explain that to Jesue than stripping a little joy from a child in a world that will give them plenty of heartaches.
Its not extremist, its just plain fact. if you tell a child that Santa is coming, its a LIE !. If you tell a child the Easter Bunny brought something for them, its a lie.
What is extreme is that you would cover it up as something else, like good nice fairy tales, that are good for the soul.
In reality they take away from the true message of the Holiday, which is EXACTLY what satan likes.
You can explain whatever you want to Jesus, I'll let Him do the judging.
But I'd rather teach my child about how Jesus can help them deal with the heartaches of the world, instead of always reinforcing that celebrating His Holy Days , must be accompanied by some material trinket in order to make them "happy" and give them "joy".
I wish I had done Easter and Christmas differently for my children , and done away with so much of the "material" goods. Thankfully as grown ups they aren't expecting an Easter Basket now, but they have no faith, one is drawn to things of the occult, because of all the "magic" in movies , such as you have mentioned, and for apparent reasons they still see Christmas as a time for consumer indulgence, and even spend what they don't have to try and live up to that ridiculous mindset and standard which was NOT SET by JESUS !
Sorry, but I have to say, I screwed it up, and regret it , by going with the "worldly " standards of celebrating Holy Days. Not saying that my children are unbelievers because of this, but it sure didn't help to strengthen their faith.
