I mean, the legal discrimination against people of color throughout history has been accompanied by extreme violence and oppression. It's a brutal legacy that cannot be overstated.
Slavery and human trafficking, lynching and extrajudicial killings, Jim Crow laws, police brutality, denial of voting rights, economic exploitation, forced relocation and genocide, invasive medical practices, cultural suppression, and educational disparities... when you whinge about "decades" of legal protections for marginalized identities, I just wonder why you think you're making anywhere close to a salient or meaningful contribution to discussions of justice.
Do you believe in punishing the son for the sins of the father? Do you believe in punishing someone who just happens to look like the sinners of the past? Do you believe that nonwhite people's ancestors did not commit the same atrocities at some point or another in history as white people's ancestors?
I'm not white, but I find ideas you espouse to be just simple racism, and nowhere close to "justice".
For much of history, most countries did not have an upper class made up of white men.
So, yes, I do believe he is "cutting in line," and should have the humility to stand in solidarity with, rather than standing on the necks of, marginalized communities. Your father-in-law is not climbing out of anywhere so deep a hole as the Black and Hispanic populations on this continent. Not even close.
Even the Gulag Archipelago pales in comparison to the centuries of slavery, genocide, rape, and disenfranchisement we have visited on these peoples in order to accrue the wealth that your father-in-law now has the privilege to work for.
Despite XIX century reforms dismissing serfdom in some regions, generational poverty of peasants kept them in serfdom like conditions up until end of WW2. And even after WW2 you could end in Ukraine with forced exports of food resulting in genocidal famine.
That Eastern European immigrant has family history of half a millennium or more in slave like conditions.
Donald Trump was in college when active discrimination by the government became illegal.
Do you think that after Jim Crow was dismantled in the 60s, that all of those people who were against it, that you see in the video footage and photos violently protesting it, suddenly disappeared?
If you are indeed honest about it, you can personally take a step back and promote anyone you want. Demanding it from others is just self-righteous and your intentions are questionable.
Still waiting for a good argument on penalizing one set of people who weren't born then in favour of another set of people who weren't born then is fixing any wrong done in the past.
A miserable person is a miserable person. Any affirmative action style policy gives less-miserable people a boost over more-miserable people.
