There is a deep, bad problem with "if you can't read cues, go fuck yourself".

What motivation do people with social skills and those norms have to help those with less social skills? Because unless there's something in it for them they're not doing it. Many of the kind of people who have social skills find hanging out with the kind of people who don't actively unpleasant. That is actually overlaps substantially with the way creepy is used; people whose social skills are so low that they are unpleasant to be around in a group, who do not have redeeming features/high status.

Also, other people's lack of social skills? Mostly not my problem. The only people I would give social skills advice to unsolicited would be those who are clearly likely to be receptive to it, i.e. people who are in a status hierarchy I'm in where I'm superior. Most people who ask for advice don't want the real thing, and sugarcoating it and getting the real message through is hard.
