Scientists disagree with each other on whether scientific theories are true. In fact the history of science is the history of overturning well-established theories for better theories that best fit the body of available evidence.
But it would be absurd to think that scientific disagreement implies that there are no scientific facts. Analogously, it is absurd to think that moral disagreement implies that are no moral facts.
