It would honestly be pretty hard for me to think of a more obviously racist website.
The thing is with this stuff… it kind of makes sense that you would find dating sites that revolve around a particular cultural or minority background. You'll find sites primarily for gay men, lesbians, Muslims, people with disabilities and so on. That's because the default culture of a "mainstream" dating site is going to be "generally mainstream able-bodied heterosexual white-ish", and people who have a cultural context that doesn't align with that can have a bit of a tough time with those.
A site focusing on "white dating"—at least in the Anglosphere—doesn't really have the same reason for existing. I mean on the surface level, something like "white dating" is the same kind of thing "muslim dating", and I could certainly see some circumstances in which it might not be deliberately bad. But the former is immediately super suspicious, and inevitably a peek behind the curtain shows it up for what it is.
