If you don't understand how it feels to need subtitles, try listening to a yanny/laurel video and see if you're able to hear both.
For us folks with auditory processing disorders, it's like the rest of the world hears yanny while we hear laurel. Without subtitles, we are simply incapable of parsing the sound as yanny.
Everyone pees. But it's not normal if you have to pee 20 times a day.
This is what I tell every person who believes that people are pathologizing normal behavior into autism. If it doesn't significantly impact your life, if it's only one or two traits, then it's not autism.
I had meltdown episodes as a child when anyone attempted to dress me in anything that had a seam that could be felt, edges of Velcro, clothing tags, untucked shirts and the sensory nightmares of cold buttons on my pants, dresses without shorts under, etc.
As an adult, I still can't wear normal bras, clothing that isn't soft, most jeans which have stiff seams on the waist, and so many materials that itch the hell out of me.
To this day, I have had friends treat me like a brainwashed social media nut for even suggesting that I may have autism. All while I'm going to the movie theater with non-polarized shades and ear plugs.
