No - and I would not characterize my lack of interest in this article as disagreement. Labeling the cost of a smile as "free" demonstrates a lack of empathy or breadth of experience that I find distasteful and would prefer not to be part of a readership to.

I think the point people have made about this is a good one, but that your take here seems very overblown.
