The current terms for non-standard sexuality is LBGTQIA+, which is an attempt to cover all variations and traits. The term is very unwieldy we is indicative of trying to mix multiple concepts under one banner. I can think of at least four aspects, each of which has a spectrum of meaning. Combining them into a single term makes the Alphabet soup above. The comprehensive alternative is to define the concept by using a negative - hence "non-standard sexuality"; making the message about what it IS NOT, rather than what it IS.
The four concepts mixed together here I tend to think of a: gender, identity, orientation and intensity. Anyone more closely involved in the relevant community is welcome to come up with alternatives.
- Gender is the biological/genetic factor.
The qualifier 'most' is important because not everyone fits into theses groups. There are a small but significant number who are XXY, YY, XYY or multiple variations in between. These are also valid but often ignored in society as being too small a group to worry about - unless, of course, you are in that group.
- Identity is what a person considers themselves to be.
I feel that in a society where male and female were exactly equal and had the same expectations, Sexual Identity would be less important. But I have no direct experience with the matter and am fully prepared to be corrected by someone who knows better.
- Orientation is which sex (gender or identity) one is attracted to.
There is evidence that Orientation is partially genetic and partially learned, and not wholly (if at all) voluntary.
- Intensity is how strongly an individual feels about Sex.
In line with all the other categories, anyone who doesn't fit the profile (e.g. asexuality) is considered with suspicion by people who are threatening by the unfamiliar.
Breaking it down this way shows that the different aspects of LGBTI etc. really cover a wide range of types and groups who have little in common, other than being outside the mainstream.
