Agreed, and given circumstances, it doesn't take more than a few successful pairings to propagate a new hybrid species if the environment is favorable to their survival.
I don't know how much we can extrapolate from modern humans to present-day, but modern psychology research suggests that what people find attractive or repulsive is extremely early-experience-dependent. I suspect a homo sapiens society living near a Neanderthal society may not grow to find them as repulsive as, say, a homo sapiens society that has rare contact with Neanderthal. And if a child was raised by Neanderthal / homo sapien parents, or adopted from one tribe to the other, I have no particular reason to assume they'd find either species repulsive.
