Subjective Morality?

[robvalue]

Yeah, if it was not possible to derive scientific facts, it wouldn’t be possible to make any of the advances in technology we have made. We'd have no way of building predictive models.

It would appear to have even greater implications. If it’s not possible, for example, to establish the mass of an object as a scientific fact, then the mass must be somehow be indeterminate or constantly changing. It would seem to be some kind of bizarre dream world with no rules.

(Technically we determine scientific facts about our observations of reality and not reality itself; that’s neither here nor there in this regard.)

PS: you seem to have admitted that the existence of "moral facts" is an unfalsifiable hypothesis, if there is no way to tell the difference between it being true or false.
