People are overly sensitive. That is a fact. However, it is also a fact that it is more fair on people to refer to conditions in linguistically neutral way. I am going to here object to your comment 'has admitted to being ADHD'. Terminology is important. Saying you have such a thing is not a confession or admission. Those imply that you are ashamed of being wired a bit differently than others. And when you seem ashamed of that, it implies you are ashamed of who you are. If you are ashamed of who you are, fine- but never because of ADHD or similar. If you're ashamed, have it be because of your choices, not what you inherently are.
Also you know what's odd is that you come up with the idea of asking if people are Autistic or have ADD/ADHD and then question the results of your poll here. Autism Spectrum has more rigid parameters that define it. To be officially diagnosed Autistic, many more conditions must be met. It is unfortunately the case that Autism Spectrum is taken more seriously than ADD/ADHD, and therefore diagnosed less. If you actually think there are lots of Autistic kids who are into Pokemon, why are you surprised when the poll shows this? I happen to know there are quite a few properly Autistic kids on here. And that topic is probably going to attract them, since it pertains to them. I can assure you that Autism is not as overdiagnosed as ADD/ADHD even now.
