a viewpoint on LGBTQIA++
Progressive people bit a bit too much focus on to exact labels and definitions.
like yes, scientifically it's helpful, but let's not forget its not like increasing the number of options from 2 to 100+, its more likely expanding from the spectrum of black to white all the way to the entire hex code, tons and tons of things included like "brick red", the point is you can be anything now, only restricted by practicality/logic (like how love is love doesn't include pedophiles as children can't consent) and besides that you can be any mixture of things.
Instead of A B and C, you can just say what you are: "I'm attracted to people regardless of gender and date based personalty not looks or sex.", if your ready to say it it's hardly much slower and far clearer than labels sometimes.
Its better to think of it as a lifestyle/way of life, expanding what you think normal to everything that works. It makes it sound so much more happy and welcoming this way as a way of life where you can be what makes you/everyone the most happy without arbitrary rules limiting your life.. :D
