ShardPhoenix, I believe that Alicorn has a form of autism (please correct me if I'm wrong, Alicorn.) Being sensitive to sensory stimuli and having aversions to some of them is common for people who suffer from autism, and I don't think these aversions are particularly easy to overcome. I'm guessing that Alicorn's aversion to sweating is in this category. She isn't just 'being lazy' and refusing to attempt to change a preference.
Note to Alicorn: have you ever succeeded in getting rid of a textural or other sensory aversion through gradual exposure?
I don't agree that we should tiptoe around someone's irrationality (and bend over backwards to try to accommodate it!) just because it has a biological cause, or because it's something associated with "our kind of people". If someone with schizophrenia came here and started posting about conspiracy theories, I don't think the schizophrenia would be a good excuse to put up with that either.
An exercise:
Name something that you do not do but should/wish you did/are told you ought, or that you do less than is normally recommended. (For instance, "exercise" or "eat vegetables".)
Make an exhaustive list of your sufficient conditions for avoiding this thing. (If you suspect that your list may be non-exhaustive, mention that in your comment.)
Precommit that: If someone comes up with a way to do the thing which doesn't have any of your listed problems, you will at least try it. It counts if you come up with this response yourself upon making your list.
(Based on: Is That Your True Rejection?)
Edit to add: Kindly stick to the spirit of the exercise; if you have no advice in line with the exercise, this is not the place to offer it. Do not drift into confrontational or abusive demands that people adjust their restrictions to suit your cached suggestion, and do not offer unsolicited other-optimizing.
