This 100%.
Sometimes you can be the hug they never got when they were a little kid and their fuckhead dad beat them instead of letting them be gay (or whatever authentic self got crushed).
I'm not saying you should put a huge amount of work into this but sometimes being kind and meeting someone where they're at even if they're super wrong does more to break the mold than to be a dickhead back. These people have a lot of experience doubling down to resistance, and if you surprise them with kindness it can shake up the whole setting.
That said, if you're kind and try to teach them, and they're still bastards/non-receptive, then move on and change the minds you can. Don't waste your time on people that don't want it.
Sorry for the long replies. I'm interested in trying to help if you are too. But I'm not trying to over extend here either. Let me know if you want to stop. I know it probably doesn't seem like it but I'm putting probably 20 min in on each of these just trying to cut them down to a "normal" size.. I could literally write a book on this!
A couple things: Idk what your scores are but basically the higher you get on the CAT-Q (2nd test) the higher the score should be on the RAADS-R (1st test). IIRC, the highest score ever formally recorded by someone allistic (not autistic) on the RAADS-R was 64. The other thing is, a lot of people don't know how either that what they're doing is "different" from allistic people, or they don't know they're doing it. For example, I wondered I was autistic for years and did test probably 5-6 times before I met someone autistic that was just like me and it all "clicked". For this reason I would recommend doing the test with someone that was around you when you were very young if you can. I will also give some examples below of some of those things that don't stand out right away if that's not possible.
That said, we have a couple possibilities.
You simply may not be autistic. There are conditions that could look similar to autism enough to make you wonder if you are or "show up" on the test but maybe not be very high on it. cPTSD is a common one if you lived in a long-term environment when you were not physically or emotionally safe. This is a strong possibility because given that you have ADHD, there's an extremely high chance you either grew up poor or had some sort of scarcity issues (one or more of love, food, shelter, etc)--this is believed to be the leading cause of ADHD. Remember that an estimated 80% of autistic people have ADHD, but that can be from the fact that life is pretty shit when you're autistic and don't know it! Less likely but possible could also be OCD or even dyslexia, both of which are SO MUCH bigger than people think.
(This one happened to me, so I'll bring it up): You may have learned the "right" answers to these so long ago you think it's the real you's opinions. Here's a couple of late diagnosed things a lot of us go through:
