Yeah, once you have kids, you realize the magic of Xmas trumps any other potential issues one might have with it.
Kids don’t think about all the issues of “free toys, stranger danger, weirdo in my house, lapsitting on an older dude”.
For them Christmas is pure magic. I would never take this away from my Kids. My eldest knows the truth, he still loves pretending and making my youngest kids believe.
Sometimes the magic of a situation is much more important than the “educational value”. You won’t traumatize your kids by having santa come and have the best morning of their entire year…
