I am kinda old, I got my diagnosis late because when I was in grade school, no one talked about autism, I was just "special" I was passed grade to grade because I would "catch up eventually" I grew up through a lot of change, I saw the LGBTQIA+ community go through something very similar to this. When we were allowed to "come out" and be less scared the community was so tribal. The gay men didn't want the lesbians around and vice versa, no one believed bisexuals existed, and you were only transexual on the weekends to make money. Or that was the thinking then.
Now we, for the most part, see the value of working together, the strength in numbers, we have shed some of the internalized homophobia and found a collective voice to fight against the attacks from the outside and stop perpetuating them internally.
This seems the same tribalism we are seeing in the nurodivergent world right now. There will be a time to come together, and fight the attacks from the outside, a time to raise our voice together and protect our own, but for now, each individual that see this as problematic must begin the cry to end the infighting and strengthen our group and show what we can do collectively.
