I agree that you don't need a diagnosis to know something is different but I can tell you it is definitely NOT a super power
I wouldn't change my ADHD for any amount of money in the world, and I often tell people who are ADHD that it is an advantage, and I have used the term superpower before.
Now, the difference between my thoughts on this and the person mentioned in OP's post is that I don't believe we should be given any special treatment whatsoever, and I've always felt this way. I actually don't like anyone even knowing I'm ADHD, as it's just not that important, and I figure you'll probably figure it out if you know me long enough anyway. I have always been in the top ten percent of pretty much any class I've taken that I chose to try at, (not something I always do, as not everything is worth effort), and I have absolutely noticed that I think faster than the average person, so yes, ADHD definitely does not hinder anyone's ability to think and process things at all, it just means it's a lot harder for me to pay attention than most folks.
I
can though..... that's the rub. I can pay attention, it's just tough, and sometimes I have to ask people to repeat themselves, or I have to reread a page or paragraph three or four times as my mind drifts extremely easily, but I can do it. Everyone with ADHD can do it, and we don't need special accomodations to do so, and we can even improve our ability to pay attention if we work on it. Listening for us is just hard mode, that's all. Hard mode isn't impossible, it's just difficult. Me personally, I like hard modes on games, and so far life has been hard mode too. The Army was hard mode for me, learning how to be a good husband and father was hard mode, all three of my degrees have been hard mode, and High School was hard mode, and these things were never difficult for me from an intellectual standpoint, (except for learning to program as I'm doing with my most recent foray back into school, holy shit this stuff is tough to learn at 38 -_-), but they were absolutely difficult from a social standpoint, and it was always hard for me to pay attention throughout everything. It was possible though. I have a beautiful marriage that took me a long time to figure out, an incredible daughter, (just got number one in her entire school for math development recently, of which I'm very proud), who's my best friend and my universe, and I've got two degrees and almost finished with a third, all in completely different fields, (Exercise Science, Business Administration, and Game Programming), and my life is pretty ok I think.
Most importantly, and I mean this, I'm finally proud of myself and who I am, and I earnestly believe that if someone made this all easier for me to accommodate my ADHD, .....well, I don't think I'd be as proud ya know? I'm proud of the fact that it was all tough for me. I'm proud that I stuck with it and figured it out. Hell, I even got off of ADHD medication when I was 17, over twenty years ago, because I wanted to be me, the real me. I'm proud of that fact too, that I've done everything I've done in my adult life, mistakes and all, without any pharmaceutical help as well.
I guess my point is that I DO consider ADHD a super power, but super powers shouldn't mean we need special attention or accomodations; it should mean that we can do anything we put our minds to as we have the tools at the ready that we must simply learn to use. We have sharp, fast minds that can easily consider the abstract and the esoteric, but with that comes the propensity for boredom and quitting when things get tough. The solution? Work hard at it! Improve! Try new things, better yourself, hit the gym, read more books, try to criticize yourself, try to see from other points of view, and never take the easy way out! It sounds like the person in question just wants people like me to be given the easy way out when we have the mind to play on hard mode, and to that I say no thank you.
If you can do it, then so can I if I work hard at it, special accomodations be damned.
