Instead of LGBTQIA or whatever insane number of lettered acronyms are created to describe the plethora of non-traditional, non-heterosexual
relationships of some people, how about call people who don't fit into typical heterosexual standards, COUNTER-SEXUAL. Just like with counter-culture, which is COUNTER to the mainstream, COUNTER to traditional most popular culture, COUNTER-SEXUAL becomes a similar word to describe anyone from that population when referring in GENERAL. When speaking in specifics then someone can still say, gay, lesbian, transgender, intersex etc....otherwise in general reference, it could be COUNTER-SEXUAL which is much more simple and to the point, more literal and less
complicated, less controversial or
uncomfortable, more neutral while still honoring the differences while trying to include all the different types of sexualities-which could end up using the entire alphabet!
