I think the issue here is that to you progressivism is a set of very specific ideals whereas to me it is a set of general-purpose political tactics. We could argue it around in circles forever, so why not cut to the meat of the issue; what would we expect the progressive response to be like if each of us were right?

Situation A: Three nationalist groups representing their country's majority begin systemic campaigns of genocide against minority groups whom they resent for their higher social standing and perceived foreignness (in reality, both have lived there for centuries). The German NSDAP targets the Ashkenazim, the Vietnamese Viet Minh targets the Hoa, and the Hutu Akazu targets the Tutsi. What do we expect the modern sensible progressive to feel?

If this is a simple question of morality, we could expect that each case would merit strong condemnation and the failure to prevent them as an unforgivable tragedy. If on the other hand Progressivism is simple political expedience, we expect our answers to break along purely practical lines; the NSDAP was a rival and is thus condemned as strongly as possible, the Viet Minh are even now an ally and thus their actions are completely ignored, and the Akazu are of no consequence whatsoever and are thus thought of only within the context of expanding the power of allied NGOs.

Situation B: Two men lead attacks on US Federal Government buildings in an attempt to spark a race war which they believed was divinely ordained, failed, and were subsequently executed. John Brown attacked the Federal Arsenal at Harper's Ferry, while Timothy McVeigh attacked the Federal Building in Oklahoma City. In both cases innocents were killed as a result of the attacks, and in both cases their actions hurt their cause in the public mind and encouraged the expansion of paramilitary police forces designed to prevent similar future strikes.

If this is a question of humanitarian ideals, you might expect that both would be repudiated for their actions; even if we hate slavery, surely a student of history should recognize that slave revolts tend to involve mass murder even when successful which means that regardless of the validity of their complaints, both were attempting to start a genocidal war. Of course, from the point of view of political expediency there is no conflict whatsoever; the neofascist terrorist is a threat and thus irredeemably evil while the radical abolitionist terrorist is a predecessor and thus an inspiring heroic figure.

Situation C: Two governments of modern first-world nations have made the deliberate descision to deny life-saving care from those seeking it for a practical purpose. The US government's Tuskegee Syphilus Experiment has denied 400 black men access to syphilus treatment so that the army can gather data on how best to treat STIs (a major readiness issue in any military), while the UK government's Liverpool Care Pathway has dehydrated and neglected 10,000(!) "dying" patients to make room for patients with better QALY returns.

If this was a case of values, we should expect universal condemnation; the TSE was nothing short of a racist massacre while the LCP crossed the line into actual mass murder. On the other hand, the US Army is a traditionally right-wing institution while the NHS is a monument to Social Democrat ideology; it would be surprising if the TSE didn't result in public shaming and calls for new boards of well-paid ethicists (read: academics) in every hospital while the LCP is met with calls for increased funding to the very organizaion which enacted it.

Obviously this isn't a perfect test of the principle; it's not particularly sporting of me to pick examples with perfect hindsight and I do apologize for that. As a rational intelligent person I know you're more than capable of stepping outside your philosophy and asking why it happens to have grown into the shape it's in, and who it's ultimately helping. As long as you've done that, as far as I'm concerned we don't disagree on anything substantive.

(Also I was hoping for your opinion on whether my explanation of the "governmental entropy" made any sense. I guess putting it in the middle of a text wall was a poor idea lol.)
