Pretty much nothing is 100% good or bad.
In many cases, accessibility rules (or fire safety rules for that matter) can prevent a business from being viable. Are we better off with a store that has a huge sign "does not meet fire code, enter at your own risk" in front of it, or with no store at all? I prefer the former.
There is positive discrimination, telling quadriplegics that they should be euthanized. And there is negative discrimination, failing to provide an ADA compliant restroom. The former is fascist, however the latter is not in my opinion. Of course it is best if all venues have restrooms that are wheelchair accessible, however the idea that any which does not provide accessible restrooms is fascist is a logical absurdity.
Lets take your argument to its end. There are 1 million wheel chair users in the US [2]. Lets just say that any venue that negatively discriminates against 1 million or more Americans is fascist. How many restaurants are there in the US that provide separate gluten free work surfaces in order to prepare gluten free food for the 3 million with celiac disease [3]? Another million people have a milk or egg allergy and need separate work surfaces for those ingredients as well [4]. I know, it's just 120 000 people in America that are actually blind [2], but not a single grocery store provides braille packaging on all their produce. All in all there are 2.4 million who are visually disabled, they should be given well lit venues, no darkness and light shows at concerts for them, they might trip and fall in the dark. But if things are going to be well lit, what about the 3 million Americans with chronic migraines (which causes photo-sensitivity) and therefore cannot bear the bright light [5]? Its literally impossible to not negatively discriminate against someone, and I've not even gotten into religious or ethical diets and norms. So is everyone who tries to open a venue a fascist?

HN has lurched to the right, and fascism is now acceptable here.
