Well I guess this is partially true. However I choose a Mac and Microsoft and Apple choose not to have IE support for Macs. So while I did choose Firefox I choose it over Safari, not IE. IE is not a choice that I have and so websites that only work in IE are not accessable to me. Not by my chioce though.
Anyway my point being that the person is not denied access based on the fact that he can't see, just the software he uses doesn't function well on that website.
There is no test in the background being run that reads like:
If user == 'blind':
So I am still left wondering if this is about blind people having access to websites or is it about forcing us to make websites work with all browsers? If they can force me to make my site work with a screen reader browser, then why not force me to make my site work for all web browsing software?
Again like I mentioned the person in question has access to Target's products and services. Just not VIA Target's website, but that has nothing to do with Target being negligent, just they don't support screen reader browsers, just like some websites don't support my browser.
