Yes--there were a coupe of posters in the "pro Santa camp" who were over the top rude. There were also a dozen or more people who were not like that at all.
Yes, there were some. Heck, the OP used the word "lie" did it not? From my perspective, there were probably a few more rude people in the "anti Santa camp" than the pro--but both sides had both rude/judgmental, and live and let live people in it.
No--but if you are seeing it as lying--and not just not a "game" you want to play with your kids, then the implication is that you feel lying is wrong and children should not be lied to. (besides, um, locking the door at night goes on for years longer than Santa in most healthy families
).
I was not thinking abotu that, but wondering about the Birds and the Bees. That is something my kids always knew the basic truth about (as in, from the time they could ask, which for DD was before 2; she wanted to know because i was pregnant with her brother). Some of the same people who were always big into being honest with their kids and not "lying" about Santa, etc were the ones whose kids believed that baby came from storks, or "when you really really love someone and you area grown up, then a baby just happens" (that one got very interesting at a family reunion when the child overheard people asking her aunt and uncle when they were going to start a family--she announced nice and loudly that they did't have one because they did not love each other enough like her mommy and daddy did. )
