I saw the main gains of the top post being the links. I don't agree that the links contain only "don'ts"... but, well, so what if they did? If there are clumsy don'ts as routine mistakes, learning to recognise and avoid them is surely an improvement?

As these aren't academic peer-reviewed articles, I can't give you objective evidence in the form of citations and impact measures. What sort of metrics could one provide that would make them more convincingly expert? If these aren't the best experts available I too would like to know who is better so as to learn more.

Can you identify even one person that has (as you put it) gained a few levels from these resources?

If you're saying you'll accept anecdotes as weak evidence, then yes, I am one data point there. :) Comments particularly on the pervocracy and Captain Awkward links contain other such claims.

As many have said - both here, and perhaps ironically, in many of those links too - it's more productive to focus on behaviours rather than on labels for people. "Creeper" is a very laden term, probably very similar to "racist" - most of us don't want to think of ourselves as someone with all the imputed characteristics of those labels, and we get defensive.

When I started being able to focus on behaviours (my own and others'), I recognised a number of ways in which my own biases, ignorance and negligence were costing me flawless victories in many social & business settings. This is why I wonder why there's so much pushback, as the upgrades in general communication/social/people skills from a good reading of privilege and social justice are useful everywhere.

Rationality & intelligence should win, right? If smart women with better people skills than us have specific practical advice, how can we lose by listening carefully and bypassing our defensiveness? Even if only 1% of it were useful, don't you want that 1%? I do.
