Don't we lie to our kids though about Santa Claus, the Easter bunny, the tooth fairy, and an invisible man/woman/being that lives in the sky/underground that judges you for everything you do?
Why yes, yes we do. Now are lies really that bad. I would suppose it would depend on the situation we're presented with. Obviously, if I just got caught in bed with another woman by my wife, I'm pretty sure that a lie ("this isn't what it looks like, I swear") just ain't gonna cut the mustard.
To make it clear. I'm not a religious guy. In fact, I find most religion funny. The first statement was not meant to be inflammatory (good god do we NYer's love to talk...). It was simply the exact thing that 99% of us tell our children when they're young, so we can break their spirits when they find out the truth. =)
