Not true. I know the internet incel virgin BBC propaganda and it's 90% bullshit.
It's wrong on many levels and for many reasons and here are a few of them:
1. Black people are often lower class and lower class sticks to lower class as upper does to upper.
If you're goal is to date lower class you're to blame.
2. Not that many blacks around in germany, mostly turks/arabs and no sane woman wants an arab.
3. Personal experience of women batting an eye on me.
Yes this happened although I didn't react of course.
