Neil Degrasse Tyson is a shitbird shill, BUT those bagging on him for not being willing to LIE to children are severely fucked up.
Deception is an un-fixable wound to any trust complex. ESPECIALLY parent-child. And this santa bullshit is usually the first lie parents tell, and as such the first time children learn (eventually) their parents are liars.
You can have the celebration, spirit, music, food, gifts, gatherings, etc without LYING.
