Nope, companies that offer goods to customers are "forced" to accomodate people with disabilities.

I know what I wrote. You're just mistaking equality for special treatment in this case. Building a ramp for disabled access isn't special treatment, it's equal treatment. You're failing to see that because you're not disadvantaged in this case. It's the equivalent of building a door, or steps, say, for people without disabilities.

It's about ensuring that everybody gets equal access to the store.

What happens once you're in the store is up to you. I'm not saying everybody in the store should be given the same amount of money or that disabled people should get to skip the line at the checkout. But if some people can't get into the store (or, for example, were denied access to the store for generations), through no fault of their own, then it's not demanding special treatment to demand they're given access. That's equality.
