We have had equal housing legislation and regulations for decades. Every real estate office must display information.
My first time showing properties to a black woman, made me uncomfortable, but I dealt with it.
She asked me questions, which led me to wonder if she was undercover, checking out how she was dealt with.
My area has some Hispanic concentrations, and some Asian concentrations, but too few blacks to be able to even find a distinct neighborhood, where they might be concentrated.
Anyway she asked about racial segregation and I told her it was largely economic, which it is to some extent.
If I had been in a position to say to her, "sorry--you don't need to look there because they won't sell to you since you are black," it would be precisely the same as me saying to her, "sorry they won't sell to you because you are openly homosexual."
I would lose my real estate license in no time, if I told a prospective client that I refused to work with them because they were black, openly homosexual, etc.
That is reality in the real world I live in.
Our civil laws are NOT guided so as to conform to religious beliefs, fortunately.
We don't cut off hands, even though muslims have that in their book, supposedly. In fact we recoil at the thought of sharia law.
The same Christians that believe the earth is 6,000 years old, believe in literal interpretation of the Bible.
Moral of the story: If you won' serve all customers who come your way, don't hold yourself as if open to "the public."
Apparently the Oregon law since at least 2007 has reflected this.
