> it used to be that if you didn’t have anything positive to say you’d just shut up and move on

While that's an attitude I've learned to follow ("If you'd don't have anything nice to say, don't say it." as my maw would put it) I'm not sure it's actually that healthy. It shuts down all possibility of (negative) criticism for fear of causing offense, or bad feeling.

Sorry, I might have worded it too generally; imho a well reasoned criticism falls under the "positive" side, unlike Evil quips and disparaging remarks.

You comment is anything but positive, and yet you have written it.

The last paragraph ("Thanks, for being today’s example. Now can you please make the effort next time?") is downright nasty.

My impression from people like you is that your kind loves writing toxic comments but thinks that covering them with a fig leaf of a supposedly 'good' cause and high moral ground somehow makes that acceptable.

On the contrary, I do think that calling out nasty behavior is a net positive. Yes, a reproach is a reproach... no need to sugar coat it, but you'd expect the same if you farted or belched in public.

Now, have a good day.

Maybe you should make an effort not to be an *ss on the internet next time as well. Wtf. This comment is more hateful and demeaning than OP. Why not set a good example instead of stooping lower.

She's exploiting a real problem (or what she deems to be a real problem) to sell her book.
