First of all, if what gets passed? Binnion isn't seeking a new law, he is acting on current ones that he believes have been violated. Again, what were you thinking when you said "If this is passed it allows the way forward for any case where anyone says something you don't like(?)"Even if this was a proposition for a new law (which it isn't), the ramifications would not be what your are projecting. This is specific, covering discrimination/defamation (the latter is already illegal, and the first is under certain circumstances). No new and scary precedent is being set.
Meriam Webster:
": the practice of unfairly treating a person or group of people differently from other people or groups of people"

In terms of the EEOC's circumstances, the discrimination that occurred is unprotected, but only because it didn't happen at, or in connection to Binnion's place of business. Otherwise, it would likely be protected under the discrimination and harassment clauses.

Racism can be racism without being illegal, as can discrimination. Coupling the unpleasantness of discrimination (even if only out of negligence) with the real chance that this was defamation, and something could be made of Binnion's suit.
Defamation:

See link above. This could very esily be defamation. Linguistically, it is discrimination. Legally, it misses being discrimination by where and who, not what.
So you agree that it is not discrimination in the sense that you can sue over. Good to know.
Basically this guy felt they were mean, they were, and wants to sue them. Well get ready to be sued for pretty much anything.
The law suit is dumb and he should lose. If he wins I'm gonna sue the Baptists, liberals, atheists, Catholics, Hispanics, rich white men, the crips and anyone else I can think of as they have all said things that offend me and are discriminatory.
