There are obviously some that will believe her and say that she is right. Myself I have never seen a Santa at the mall that was anything other than caucasion, but that doesn't mean that I don't think that Santa could be any other race. It's really a stupid thing to say to tell someone what they should or should not believe.
Some might think one way, and others might think another way. As for my kids, their thinking is entirely different.
Whatever color your Santa is, Merry Christmas.
