This is true. Same with Jew-haters, as there will always be antisemitism.1. In my opinion (opinion!), the "racism" problem is insoluble.
2. Maybe the OP's prospective landlady did not like African Americans (or Asian Americans or Hispanic Americans for that matter).
3. But maybe the landlady lied about a vacancy because she was afraid of losing her job and apartment house.
4. Maybe she has non-Caucasian friends; maybe she patronizes non-American food restaurants; and maybe she has even insisted that her church welcome non-Caucasian worshippers.
5. But she is terrified that if the OP moves in, then others of that ethnicity will move in.
6. And she is terrified that soon some new tenants' relatives will move in; there will be loud parties; drug dealers will come around; dangerous dogs will roam around, etc.
7. And there will occur "white flight."
8. After all, we know that African American celebrities almost all leave their family neighborhoods for nicer and safer areas.
9. In my opinion (opinion!), African Americans will always be subject to discrimination -- even when Caucasians are reduced to a small minority (sometime in the next century) and Hispanics become the largest single group and possibly the majority of Americans.
10. Yes, it is very sad. But -- as you young people say -- it is what it is!
The best thing to do is rise above it. Do things that will lead to a successful life - like refraining from having babies before marriage, make sure you’ve been educated or trained for a career or trade, obey laws, work hard, and respect authorities (be they your boss at work or cops on the beat).
Of course, one must report hate crimes that targeted you, if they happen. I wish I could have proved who it was who scratched JEW on the hood of our brand-new car.
