I think there are several problems here. But I see from the rest of your reply that you consider terms like 'illness' or 'defect' are pejorative. So I guess a problem is whether some or all of the conditions we are discussing
are indeed defects or illnesses. They do seem to be so as far as I can tell. But that's not a pejorative comment about a person, but an assessment about their health.
But why do they think so? Is it because some statements made by a psychological association? But what are those based on?
Some conservative philosophers and the like claim that the purpose of sex and/or the sexual organs is reproduction. I think there is no purpose other than whatever purpose we have, but there are functions, and surely one of the functions - indeed, the main function - of the sexual organs is reproduction. However, the same organs can have more than one function. In our closest relatives - bonobos - sex plays a number of very important social roles. As far as I know, bonobos are bisexual, and I would be inclined to think a bonobo that fails to be bisexual probably has some kind of illness, defect, etc., that makes it considerably less capable of living in bonobo society (though I'm not an expert in bonobos, and my probabilistic assessment is based on the limited info available to me). If it is homosexual, then I would also be inclined to think something is probably not working properly in re: reproduction.
Now, humans are not bonobos, and I wouldn't make that assessment regarding bisexuality. What do I know?
But if we're talking about homosexuality (defined as a lack of opposite-sex attraction), I think there is a good chance something is not working properly. Now I'm not suggesting that properly functioning humans at every time in their lives would be sexually attracted to individuals of the opposite sex. Under certain conditions, no sexual impulse whatsoever is to be expected. But a lack of attraction towards the opposite sex even throughout their lives and even when they're not in danger, or having to care for children, etc., seems to me like something not working properly, and I have not seen good reasons to believe that the assessment is mistaken.
Granted, psychological associations - well, some of them - claim that homosexuality is not an illness or disease. I used to believe them, several years ago. But after carefully considering their claims, I see no good reason to believe them anymore. I'm not certain that they are mistaken, though I think that that's more probable than not. Of course, in the end, my assessment is probably another example of the way we assess illness and health in general, which is intuitive on the basis of the available information on a condition. What triggers my assessment is probably speculation on my part that comes later.
Of course, this creates more problems, such as:
1. It follows from your statement that I'm not a person who might consider himself enlightened and reasonable. I consider myself reasonable, but I don't know what 'enlightened' would mean in this context.
2. There is a high probability that just replying to your reply to my post in an honest manner (i.e., this reply) will get me strongly condemned by several people, and will end up getting me into a long debate in which I'm mostly defending myself (rather than discussing the matters at hand), and trying to find an acceptable way out of the thread.
I don't see a practical solution for this kind of problem.

There would seem to be room to say that some unusualities or atypicalities are not illnesses or defects or abnormalities in the pejorative sense. We might even call some of them enhancements.
Sure. An IQ of 200 is abnormal. And having superpowers would be abnormal (even if it's not possible, that tells you it's not part of the meaning of the term).

Which raises the question of who decides which is the correct term. The individual? Society? In terms of survival or evolution, no one 'decides' obviously, but then that would merely be a neutrality.
My take on this is that the meaning of words is given by usage, but there are words that have synonyms in different languages and have the same meanings across human societies (to the extent that words can have a consistent meaning), whereas others do not. Examples of the former are, in my view, terms like 'morally wrong', 'immoral', 'healthy', 'ill', 'illness', and maybe 'female', 'male' and 'water' (in their colloquial senses). Examples of the latter are 'car', 'phone', 'cat', 'horse', and technical terms.
As I mentioned, 'ill', 'illness', and also 'defect' are examples of the first type of terms. So, the issue is whether those are indeed defects, illnesses, etc. This is assessed of course intuitively, though the intuitive assessment depends on the information available to us. Note that this is how whether a condition is an illness has
always been assessed. Humans were capable of identifying many illnesses before DNA was discovered, and in fact even long before viruses, bacteria, gametes, etc., were discovered. Modern science allows humans to treat some illnesses much better than before, to understand their causes, etc., and in some cases, indirectly to make more accurate assessments as to whether some conditions are illnesses, by means of having more information about those conditions. But in the end, it comes down to an intuitive assessment of whether the condition is an illness, using whatever built-in illness-detector humans have and the available information (which indeed grows with science).
Now, if this is
not how it works and words like 'illness' or 'defect' change meaning from social group to social group (of English speakers), and different societies did not have words that meant the same as 'illness' or 'defect', then it appears that there are some serious problems.
I. Widespread mistranslation, as different languages do not have the same terms (i.e., words with the same meaning) in this context, but translations occur as if they did.
II. Widespread miscommunication: maybe homosexuality is a defect according to the way some people use the word 'defect' in English, but not according to the way others do. If so, they're talking past each other - rather than disagreeing - when attacking each other and attempting to debate whether homosexuality is an illness.
Now, I think this does not need to lead to an error theory: as long as people in each social group are tracking some property reliably and that mostly respects their paradigmatic cases classified as 'illness', their words probably succeed in referring, even if they're mistaken about the meaning of the words as used by others. But the problems I. and II. above are pretty
massive. Still, if they are, well such is life. But I reckon this is
very improbable.
What if the meaning does not fall into any of the two categories I described above? Well, I don't know what else might be the case, but I would listen to alternatives if presented.
