> Suing every hole in the wall out of business is hardly in line with reasonable accommodation.
Suing is the enforcement mechanism chosen by the Israelis and the US, not the reasoning behind the requirement. The reasoning is: The disabled should have equal access to dining and it's not an undue burden to expect ramps outside of businesses. Most of the developed world is like this.
You might disagree with that reasoning but clearly a political majority in the US didn't and doesn't.
