the problem with this line of argumenting wrt abortion policy is that the "pro life" states consider fewer abortions a good outcome, generally. thus, similar to your emancipation example, *according to them* this policy is benefitting minority populations/poor populations disproportionately. i don't take their statements at face value, but it seems conspiracy-theory level of reach to think that texas legislature passed anti-abortion law with intention to harm black & hispanic populations with the presumed outcome of having more of those populations that resent + vote against them. that's a really strange "explanation", mechanistically.
there are other holes in the argument as presented too. for example, you correctly point out that many variables are correlated to each other...thus it does not follow even in principle that a policy that explicitly benefits poor is also necessarily designed to attack any arbitrarily selected co-variable. people in this thread didn't claim the policy was anti-race, anti-poor, and anti-8 other things simultaneously or similar. the discussion singled in on race, yet the limited information we have does not support it, and arguably presents an outright opposing explanation more convincingly.
again, disproportional effect has been demonstrated as refuted *by itself*. i'm still open to a mechanistic explanation, but you're still repeating the observed disparity and conjecturing the motivation for policy was therefore racist.
this directly contradicts the supposed mechanistic explanation you give though :/. fewer abortions = more people, objectively. insofar as there are disparities, the stratifications getting fewer abortions as a result of the policy will have proportional population increase more.
it isn't though. "i think their motivation is racist because we observe the disparity" doesn't change the assertion, at all.
outcomes themselves are not "racist", by definition. it is the policy that may or may not be racist.
if you took this rationale to its logical conclusion, you could literally claim every politician is racist, period. no exceptions. because we observe disparity of outcome from almost every policy wrt race. an "explanation" or model that (according to the arguments presented here) literally predicts hilary clinton, donald trump, desantis, and ortasio-cortez, whitmer, and kamala harris as
identically racist, probably has something wrong with the model. no matter who among those names you like, if any, a model that uses rationale which applies to them equally is probably not functioning properly.
even in the context of abortion specifically you can make the same case against all of them, because all of them advocate a policy whereby, depending on your opinion of abortions in general, disproportionately impact some racial group.
so let's use a "mechanistic explanation" that doesn't actually equate aoc to trump and biden at the same time please.
this is consistent with my argument, though the conclusion you come to only follows sometimes.
more misinformation, in this case quoted is
objectively false. maternal mortality is not much higher for "people of color". it is higher for black americans, specifically.
Maternal Mortality Rates in the United States, 2020 (cdc.gov)
notable that hispanic mothers had an even lower abortion rate than black mothers in the earlier article, too. so that doesn't predict this outcome either.
you are correct to note that it's unlikely purely natural/genetic factors leading to a different observed outcome. but that doesn't mean that it's useful to misattribute cause without basis to do so. in fact, doing so is harmful.
