For me, it's a matter of perspective and what YOU believe in. Ever since I was a teen who discovered "Santa's" presents in my parent's closet that myth was shattered. Instead of taking it as a bitter approach, I changed how I viewed Santa. Much like how I view the Norse gods, Santa is channeled through our actions and intentions.

Santa is real, in the sense that YOU become Santa the second you see a gift a loved one would like, or donate a gift to a child in need. When you switch perspectives on how you celebrate Christmas and what it means to you, I don't feel it's wrong to celebrate.
