As someone with ADHD, I hate the "RTFM" motto

I'm a student of software engineering. I'm not a programmer yet, but I use software that is common among this crowd, like i3wm, Neovim and Emacs. I know how to find and read documentation. I've read the obnoxious How To Ask Questions the Smart Way. Every time I encounter an issue, I do my diligence. I go through the manuals, I google, I read the docs. My main editor, Emacs, has an extensive manual, with plenty of accurate details. I get that's a huge program (more like a platform, really), but let's just say that a black-and-white 650 pages PDF is not the most ADHD friendly thing in the world.

I'm aware that I chose a career that requires plenty of reading, but I happen to like it a lot and it seems like I have some aptitude for it. I had similar issues in my previous activities anyway. But it's discouraging trying to understand programming and complex software, only to be repelled by people who think everyone has their ability for concentration. Sometimes I completely lose track of time. I can sit on my computer and hyperfocus for up to 48 hours with 20 Chrome tabs open non-stop and Netflix on the background. I may seem productive, but I'm not reading anything. Maybe I read one paragraph or two, and 30 seconds later I can't remember what I was doing. But I still have tasks to accomplish, and sometimes I need help to find useful information on a 700 pages manual.

Luckily I have a great support and determination and have accomplished a lot, but my peers have no idea what I went through to get to where I am. What I don't have in natural born skills I compensate with a lot of raw effort. Everyone has their difficulties and I'm not seeking compassion, but I'd like to suggest people think twice before dismissing as "lazy" someone you know nothing about. That person might have a mental disorder, a reading disorder or even an intellectual disability. Do you wanna be the guy who told a dyslexic to just read the fucking manual?

EDIT: of course I get that time and energy are limited commodities... my point is: don't be an asshole about it. Do what you can and you wanna do, but there's no need to use hostile buzzwords when you communicate with less knowledgeable people. You're not even forced to answer... I much prefer not getting an answer than getting a hostile one.
