However, simply put, were the question proposd whether our sexual practice differed from the norm, we'd all have to put "yes," and that would make us deviants. Just because we don't like the connotation attached to it doesn't mean it's not true, unfortunately.
But
why are you so attached to that
particular word? "Deviant" denotes "different," but it connotes "
bad-different." It connotes harm and ugliness. There are dozens of other words that will do just as well, "different" being probably the most neutral. Anormative, uncommon, unusual, diverse, variant, etc., are rather more positive. They're
just as true, and they don't piss me off, so why not use one of them?
English is an immensely rich language, with positive and negative and neutral synonyms for most words; there's absolutely
no reason to cling to a word that has obviously offended the people to whom you are speaking... unless your intent
is to offend.
Furthermore, I think the use of "deviant" is
not true, connotative or otherwise. Being a genius (IQ over 140), in your terms, is deviant, because it is Other Than The Norm; being able to read is deviant by your terms, being extremely good-looking is deviant, eating with a fork is deviant. None of these things are particularly normative, I expect they describe a rather wee minority of our species.
But we don't generally
call geniuses deviants, do we? We usually reserve that word for psychopaths. We don't think of beautiful people, literate people, and well-mannered people as deviant, do we? Because they're not deviant... in many ways they are advanced, aren't they? Most of these things are considered, in our culture, rather nice things to be.
Perhaps in the scientific community, "deviant" might be a perfectly benign word; but here in my world, the world of English-language literature and communications, "deviant"
is a negative word, a word that I am fully justified in finding offensive when applied to me.
I am telling you I find that term offensive; if you persist in using it on me, I will be offended. That's all there is to it.
And yes, I
will refrain from calling people "gay" if they don't like the word; that's called good manners (though I won't call anyone g0y, for reasons I have elsewhere belabored at some length). I will refrain from referring to African-Americans as niggers, even though I don't intend it as an insult and even though they call each-other that all the time; that's just common sense.
Words have power, and you have to learn to wield them properly before you can communicate your feelings and ideas. If you use offensive words, you don't communicate your ideas, you don't build bridges: you just piss people off, which destroys your credibility and hurts your cause.
