People have their preferences for who they want to match with. It isn’t the fault of dating apps that there are people who have a preference for dating within their race, or people who have a preference for dating a different race in particular.
These preferences exist in human beings with or without dating apps. People too often forget that dating apps are businesses. They cater to consumer demand. Since there is a consumer demand for race-based dating apps, they now exist in the online dating world.
The consumers who choose to join these race-based dating apps are doing so because said dating apps meet a need. This is a need that they had before the existence of dating apps. If dating apps disappeared tomorrow, this need won’t disappear. It’s in our nature to seek out a mate that looks like us.
And those who choose to seek out people of other races have their reasons too. After all, you can’t force people to be politically correct in who they deem attractive or worthy of lifelong companionship.
There will always be some form of polarization between the races.
Again, it’s human nature.
We all have our internalized prejudices about people of a different race. So do you. So long as humanity exists, this won’t change.
In lieu of getting too caught up in the weeds about this, focus on finding a compatible partner that works best for you, and let other people do what works for them.
