Your personal Tumblr journey starts here
As someone who has an 'invisible' disease, and who seems 'too young to be disabled,' when I was still on my journey to finding the right meds, I got a thing that allowed me to use disabled spots. (I now don't need it, as I am in remission.) If I was not in the great land of Canada, where our (unofficial) slogan is, "Be nice, we're Canadian." (at least what some people say) someone would have probably asked why I was using a disabled spot or that I didn't look it. Just because I'm not using a wheelchair or crutches or 'look disabled' doesn't mean I'm any less valid.
i hope you guys know defending disabled people's right to exist in public also involves defending disabled people's right to exist in public in ways that others might perceive as annoying, unpleasant, uncomfortable, and inconvenient at times. a blatant example is the "slow walker" thing. someone with tourette's syndrome who has issues with verbally ticcing is likely going to have trouble staying quiet in a public space where they're expected to be and doesn't deserve to be met with anger or punishing behavior for it. autistic children (and some adults) getting triggered into meltdowns due to an overstimulating environment. people with hearing problems having their phone on speaker while on a phone call. a wheelchair user taking up part of the road/sidewalk/aisle. people with autism, adhd, hearing problems, or other things that affect volume control having loud conversations. someone audibly talking to themselves, which can be attributed to many things. motor tics. dyskinesia. ataxia. pseudobalbar effect. the list goes on. some of thus may even be potentially triggering for your own issues if you're someone who's also mentally and/or physically disabled, but if you're well aware of how you can't help your response to it, you should be equally aware of how others can't help themselves either. people who aren't able to be disabled quietly and conveniently don't deserve to be punished or met with anger (or turned into a spectacle) for not deciding to shut themselves away.
