I think you've just hit one of the nails of this thread's title right on the head.
That last sentence is a complete denial of all the autistic people here who have a problem with that specific thing (and that's a selection of members here, far from all), and strikes home at one of the fundamental problems, you've said this as a statement of fact so indisputable it needs no explanation - but for those of us for whom this is a very real problem, how do you think we should interpret that statement? Is it saying we don't actually have a problem with this, it's something else, a sham, an excuse, a diversion for something, what do you think it is?
Some of us have grown good at faking it in some situations, but simple? No, not at all (though I bet there are also some here for whom it is simple), but the biggest part of the issue is the unquestioning assumption that if it works for someone in a certain way it must work for everyone else the same, and I experienced that miscomprehension myself and spent most of my life totally unaware that my actual perceptions were really quite different from 99% of the population, so I appreciate how powerful that cognitive bias can be, but in the end much of what we think is common to almost all of us, is very much not the case. This isn't just autism either, although autism tends to relate to people with more extreme differences than for those described as normal.
