I could ask the same of your statement, I remember when it was just LGB, and the amount of infighting and name calling everyone went through when new letters were added or proposed, but the general sentiment was the same whenever that argument came up. ”there are too many letters being added and we feel this cheapens our movement we've worked so hard for by allowing other groups to ride on the coattails of what we've worked for"

Now of course that's gatekeeping, and forging that path is of course going to allow others to travel it as well, which is perfectly fine. However let me use an extreme example to show you what many were afraid of at that time, say it at one point became 2SLGBTQIARE+&ODM

This is ridiculous right? How is the average person, the person you're trying to convince to accept the movement, going to remember all that? How are you supposed to form a cultural identity if you keep rebranding over and over to the point where you have to be deeply immersed to understand the nomenclature?

Thus the + was added, being all inclusive and finally seeming to be a change that not everyone and their mother was up in arms about. To answer your question, that is how I came to my conclusion, having lived through it and put a whole lot of my soul and energy into this movement I feel pretty confident to say that LGBTQIA+ is just fine.

If you disagree with that, well then you do, I can't stop you, but hopefully you can see where I'm coming from
