There are some groups that try to bring it up from time to time. I know there have been some productive discussions on how the industry handles some of these things despite the history real estate has with things like redlining and blockbusting. Skirting fair housing laws is absolutely still a thing and many brokers are starting to come down hard on it especially with regard to the buyer love letter thing.

It's really a difficult thing to address because even if you sort the industry side of it out you still have buyers and sellers who are more than willing to casually engage in racist behavior. Sort of like the big galaxy brained response to my post saying I'm a bad agent because I'm not okay discrimination or something.

I think Housing Opportunities Made Equal still does matched-pair testing to build cases and try to discourage discrimination in the first place. They rely on volunteers to do the testing. https://homeofva.org/get-involved/become-a-tester/
