I'd call it reductio ad absurdum personally, an application of your logic elsewhere to reach absurd conclusions. And the existence of inter-generational effects are the undisputed facts I started with, not the conclusions reached via your logic, which are that the existence of these effects support the charge of systemic war/famine/etc. Whether it's just semantics depends on what you think the supposed existence of these "systemic evils" requires morally.
Not really. You've said that because the difference between the intergenerational harm caused by "other crappy things" and 400 years' worth of racism is only quantitative, the intergenerational effects of "other crappy things" ought to be considered systemic. Your logic implies that because driving your car at 5mph and 100mph is only a quantitative difference, driving at 5mph ought to be considered "speeding." Or because the difference between heating cold water 1 degree and 100 degrees is only quantitative, cold water heated 1 degree ought to be considered "steam." Quantitative differences eventually become qualitative differences; that much should be trivially obvious.
