I teach my kids not to back away from falsehood, to confront and defeat it with the truth.
I couldn't really give a rat's rear end about your Santa Clause phantasm or the little elves and fairies, but when my children ask me about Christmas or religion I hand them an old, magnificently gilded Bible from the mid-1800s and let them decide for themselves, because I ultimately cannot choose for them or anyone else.
Translation: I've taught my kid to be obnoxious and to butt their little noses in where they don't belong.

So when you children, let's say two to six years old, (the age this entire post is about) asked you about Christmas, you hand them your gilded Bible and let them decide for themselves....
I was suspicious you weren't dealing with a full deck, now I'm positive.
So your child runs into a relative who has a new hairstyle and a new outfit on. It is the ugliest outfit that your child has ever seen. Now the relative asks your child "What do you think of my new outfit and hairdo?". What does your child say?
Your child could be honest and say "That is the ugliest outfit I have ever seen." However, that could deeply hurt and offend your relative.
Now, your child could also say something more tactful like "It's not as pretty as your smile." That would not be a lie, and it would make the relative happy.
There's honesty, and then there's tact. The teacher in this case was not tactful.
