Hmm. See, the example in the original thread was a practical one.
In the situation where one person is producing a meal for 6 people with 13 complex dishes out of a domestic kitchen, and one person isn't, the logical solution - the "better way to do things" - is that the additional different meal be produced elsewhere by the person not doing anything.
However, Lashes' contributions to that thread went approximately thus:
L: "Of course OP should produce an extra meal, how is that so HARD!"
13 other posters: clear, logical explanations of why it would be hard, with simple, logical alternative for fussy eater.
L: [ignores logical answers] "It's a simple request, can you cook something plain yes or no. If the OP says no I would think that's unfair"
23 other posters: challenge L.
L: claims it's all the fault of OP for not communicating clearly and being willing to say no.
33 other posters: point out L is not being consistent or logical, and has changed her tack from criticising OP for not producing the extra meal, to criticising OP for not saying no to extra meal.
L: starts throwing round words like "exclusion".
So for all this yelling that people are not saying what they mean, and she can't be a mindreader, that's not what's going on here. No mindreading is required: simple, logical explanations have been given.
And Lashes's questions are not of the I-need-information type. "Is that so HARD" has no purpose but emotional manipulation.
So I'm not seeing someone merely struggling to cope with social conventions she doesn't understand (and god knows, I'm in that category myself - it's a source of grief to me that I hurt my friends by not being able to read them).
I'm seeing someone very effectively using manipulative language and behaviour to get what she wants. Lashes even said she would badger people until they changed behaviour to what she wanted (which she defines as a "better solution", though to an observer it might not be). Her targets will give in to bring the disruptive badgering behaviour to a halt, not because they agree with her.
So I am seeing a lack of understanding here. But it's not "I don't understand what other people mean."
It's more "I don't understand why other people don't understand that the world revolves around me."
