My point is: you assume that reducing the murder rate at any time is (factually) a morally good thing.
No I am not. I am assuming that X causes Y% reduction in harm is a FACT.
And there's your confusion: 'harm' isn't a property. It expresses a judgement on an alteration. An alteration from being alive to being dead may not be to suffer what we call harm. You just assume that it is, without justification. You smuggle in a value-judgement and pretend it's a fact.
Subjectively - this reduces MY risk of future harm by Y%! Subjectively, making sure that we do X is a pragmatically beneficial TO ME!
I don't give a rat's ass whether it's 'right' or 'wrong' - it's pragmatic! I wish to reduce the risk of harm upon myself.
Same mistake. And 'subjective' means 'relying on judgement, belief or opinion' - unless, of course, you're using the word in a different way which you haven't specified. Absent that clarification, what you say is nonsense. A reduction in your chance of being murdered has nothing to do with subjectivity. It's a matter of fact, as you've agreed. Whether harm and benefit are involved are moral value-judgements which, again, you pretend not to be making.
I think the same can be said for most humans? Through intersubjective consensus the 'no harm' principle emerges which makes it objective.
Much like the principle of parsimony confers 'objective factuality' to simple theories.
Same mistake: 'most humans think that murder is harmful, therefore it's a fact that murder is harmful'. You claim not to care about right and wrong, but then use the words 'harm' and 'harmful' perfectly normally. And to say intersubjective consensus produces objectivity is to ignore the ordinary uses of those words. No good bleating that you can use words any way you like, or that they don't or can't mean what we ordinarily use them to mean. Either clarify the non-standard way you're using them, or don't use them at all.
The claim that the principle of parsimony confers factuality on simple theories is so full of misconceptions that it's hard to know where to begin. As usual, you disgorge these deepities as though they're indisputable facts.

My point is: you assume that reducing the murder rate at any time is (factually) a morally good thing, without justifying that claim. Just saying that to reduce the murder rate, now or in the future, is a moral fact is patent nonsense. And appealing the 'no harm principle' just begs the question. That we should do no harm isn't a fact - it's a judgement. Ignoring the is-ought barrier doesn't make it go away.
That barrier doesn't exist. For many an OUGHTS have become IS without prior justification. For example we OUGHT to have laws and axioms of logic...
The axioms of logic are there by pragmatic consensus. Judgments of their own right.
No, you really don't understand the issue with logic. Having settled on a set of rules by which we play the game of using language to talk about things - and your favoured constructivist logic is just one such set of rules - we can then follow those rules to make true factual assertions (true given the way we use the signs) or express value-judgements, such as moral judgements. But there's no 'ought' involved in the adoption of a logic. And what you say next demonstrates your misunderstanding.
If we were as concerned with the is-ought gap as you seem to be - we wouldn't have logic to begin with.
And since I no more have to justify my principles than you have to justify your logical pre-disposition. I evoke the 'no harm' principle.
You are free to reject it like I am free to reject all the principles of classical logic and the principles by which you assert 'factuality'.
Before firing back in a rage in order to show that you're absolutely right and can't have made a mistake, and that I'm a hopelessly stupid idiot not to see how brilliant you are and confess that I've been wrong all along - please could you think on it a bit longer and reason it out more coherently.
