You try help someone based on their CURRENT circumstances, not based on their relationship with someone who died 200 years ago.
Completely ridiculous, what about those whose parents were drug addicts, or were kept out of school, or were just purely unlucky to be brought up in and surrounded by poverty. You'll find there are many, more contemporaneous, reasons for suffering and that there are many people suffering that do not have any previously persecuted ancestors.
Address their current situation without bias or favouritism.
You claim I'm being disingenuous and then say this as if I haven't been this entire time referring to historic injustices AND THEIR ONGOING LEGACIES. Nah, y'all just prefer to selectively ignore that part.
You can measure someone's current suffering, resolve that (and it can be done in a much more fair manner).
