Scientifically species classification is by successful breeding. We wouldn't be able to test it if a line had died out but all modern humans are reproductively compatible so they're all the same species.
Old homo sapiens and neanderthals were only partly compatible so they're their own species.
Some studies say mixed race modern humans have worse health than purebreds, but only slightly and it doesn't stop them breeding. If true that's the start of speciation.

It informs what kind of person you are, and how far you are willing to skew facts to justify your prejudice, so I would say it changes everything.
