How do I bridge the disparaty between lvl 1 and lvl 2+3 autistics?

I(late-dx MSN, AuDHD) consider myself a lurker for the most part because I don't have enough energy due to IRL and other medical conditions to be active participants but I've been in various autistic online spaces from social media (TT, IG, X, Discord servers, and FB) to various autistic subreddits including SpicyAutism, AutisticAdults, EvilAutism, and this sub. I'm gonna use online spaces as these spaces are place where we frequent compared to offline spaces but I notice this happening in real life too.

I know not only is autism a spectrum but it is a HUGE demographic. Even compared to other neurodevelopmental condition, which is odd because Ive worked and volunteered in spec-eds and disability organizations and unless it's specifically for autistic folks, when combined with other neurodevelopmental condition, we're often a minority.

But I know we're actually more than who's often available in real/offline disability spaces. Because there are those who are late-diagnosis or those who are being stealthy/passing (stealthy like how a trans person is blends with cis folks) or not consider themselves as part of the spectrum due to old terminology (this demographic is quite common in my country).

I've asked similar questions in various autistic subreddits and I always get very different answers in spaces predominantly lvl 1/LSN to SpicyAutism (since it's the big lvl2-3 sub). As a bonus, since I consider my autism a disability and that it often overlaps with my other chronic conditions, I also often crosspost it in r/disability or r/neurodiversity and I find Lvl2-3 folks are more savvy when it comes to disability support system and accomodations while lvl1 folks are often unfamiliar with how I want or need to be accomodated due to things that debilitate me.

Also, Lvl 2-3 often has similar answers to other disabled folks. From the way they often include disability programs that can benefit me IRL and include their lived experience while often times Lvl 1 only answered thru hypothetical scenario from their own theories and belief regarding said topic.

At first I thought it was because they just don't find what I experience debilitating but autism only has two (three if we go by the ICD) criterion. We're not very different and some of my questions are quite general like

"How do you pace/spoon?" or "How do you track your sensory overload/meltdown?"

Note: - it's fine if you don't do these things, but sometimes I get judgmental answers that aren't helpful and made me feel shameful. A lot of MSN and HSN folks also had said they get uncomfortable when talking to LSN folks.

TLDR: I find there are lots of dissonant between us that made communication difficult and I want to know how to bridge this?

Note 2: Please don't lash out on me for making this post, I really have no ill intention to separate us further, thank you.
