Without getting too political, I'll make the passive observation that the fact that some people see this as proper and reasonable conduct while others feel like they're being lectured at in a mildly condescending way explains far more about polarization between two groups of philosophy in America than one being dumb/evil and the other being righteous, as they each like to believe.
I think this one is a little of both - I think everything about the article is well-intentioned with a noble goal, and also have a taste like I was just scolded by somebody who has delusions of being my authority figure after reading it.
