"he is going about it the wrong way"
Using his free speech rights is going about it the wrong way?
No, being a jerk is going about it the wrong way. This man is anything but humble. No one but small children believe in Santa and you can believe in Santa as a child and still be taught the lessons of Jesus that will last your whole life. To stick up for this guy is wrong-headed, let children believe in the "magic" of Santa Claus for a few years of their life. Relax
I hope he doesn't mind me erecting a Satanist porn billboard on my property that he drives his children by.
