I figure the facepalm one is the most likely to be used to annoy people
I think it quite the opposite. Facepalm seems to be one of the more often used emojis here. Perhaps though with explanatory text. So far I have not seen anything that warrants it. I do not see it as annoying. More just a statement of one's feeling.
I used sad above for the first time. There does seem to be an over sensitivity to some feedback. When I was little the Bambi quote "If you can not say anything nice, don't say it." Seems to be the what the older generation did.
This thread, which I keep saying I will not bother to read and do from time to time, Does imply anger at things beyond one's control. When though is it anger at the poster and when at the subject is hard to say. This one clearly seems to be anger at the subject.
I live around 20 to 30 miles (40km) from downtown SF. So it is easy to see a local attack from such reports. That the suspect is from Tracy just shows how easy it is for people to get about in this area. Tracy is close to Modesto where American Graffiti was set, and in ways the inspiration for Mos Eisely in Star wars. The tough place were one could get shot if someone did not like the look of your face, or where you are from.
I do think that future generations will romanticize such people the way Highwaymen and Pirates are romanticized. How then does some of this not imply the shoot first attitudes of the wild west culture? Dirty Harry or the Streets of San Francisco?
The celebratory culture (of the gladiator) is also at play here in this latest indecent. While we may not be as bloodthirsty as the Romans were (Our fantasy cinema would suggest otherwise) We still do reward physicality with fame and fortune.
I personally am looking forward to seeing the facepalm used in replies.
