You sound like one of those chud gamers who thinks making games more inclusive for other people detracts from the purity of the game. It's ablebist bullshit.

a fuckload of books and movies don’t hold my attention, should everything be re-edited to suit my neurology?

"There's a fuckload of places around the city that are wheelchair-accessible, should every public building be re-engineered to suit me just because I'm in a wheelchair?" A book or movie "not holding your attention" is a completely different thing than if a book or a movie didn't allow you to set it down or walk away from it. If a movie forced the people who wanted to watch it to do so entirely on the terms of the producer, like say, not letting people fast-forward through a scene with intense flashing lights, then yes, that's ableist and that movie should be criticized for being ableist and a version of it should be made so people with epilepsy could watch it.

You might as well ask for the spiciest food to cease to exist, to accommodate normal people, as though the vast majority of food is not spicy at all.

This is such a bullshit analogy that totally misrepresents what we're saying. ("We" being those of us who think games should not be ableist). We're not asking for spicy food to "not exist" in that we're not asking for your precious games who don't want people to be able to pause them to "not exist." They can exist just fine, as I described above, it doesn't have to be either/or, so you should stop pretending like it does. Just as a spicy food dish and a mild version of it can exist simultaneously. In fact it's funny that you'd even use that as an analogy since every restaurant I've ever been to gives its customers the option to order a hot or mild version of whatever spicy dishes it has on the menu.
