You don’t see your system as broke because you are brought up in it (boiling the frog)
Just for the sake of highlighting this phenomenon:
Is Obama white?The prevailing idea of "whiteness" is a racial construct with subtle racist tones. It is an arbitrary edifice that a child is only white if his parents were both white. If one parent is black the child is black. This fundamental attitude is nearly universal and is hardly even questioned, despite its clear insinuations. Just the basic and universal pattern for applying "whiteness" to offspring, promotes a perception in which whites represent a status of purity, while minorities contaminate that purity. This can feed emotional concerns of racial rarity akin to pure-breeds, play on fears of eventual annihilation, invoke sentiments of race preservation, etc.
To be clear, calling Obama black doesn't make you racist. This example was just meant to illustrate how easy it is to adopt a racist cultural norm, probably without conscious consideration.
Show me where this broad spectrum oppression of all forms is in the U.S.?
As for addressing the crux of your request for widespread discrimination, I'm not sure what evidence you would even consider valid. If bigots are mistreating and slighting people across the nation to the extent they can get away with or not notice themselves, the nature of the claim practically requires omniscience to prove. Only probabilistic arguments can ever be made for or against the hypothesis. I base my beliefs on probabilities, but would you accept:
- An avalanche of credible anecdotes or accounts from personal witnesses? If you wanted, you could dismiss anecdotes as not technically proof. Just weak Bayesian evidence because they are just consistent with the hypothesis, but not proof.
- An appeal to the known human psychology that we have rampant cognitive biases, predisposing humans to discriminate, which requires an active educational intervention of those biases to prevent?
This kind of evidence clearly establishes a societal default that, unchecked, a nation will produce many bigots. Leveraging the fact that cognitive biases are not common knowledge nor included in school curriculum, is strong reason to suspect bigots are widespread, but that is inductive reasoning, not rigorous proof. - How about evidence that massive portions of the public holding bigoted beliefs and/or subscribing to bigoted ideologies? You could argue that his is technically not discrimination, even if it is the primary motivator consistent with (and predictive of) discrimination. Still not technically proof, just statistical correlation.
I will delve into that last one for convenience. The Muslim ban comes to mind.
Trump called for religious tests at the border, argued for 6 months for a complete shutdown specially blocking Muslims from entering the US, pushed for mass surveillance on Muslims nationwide, and proposed a Muslim registry.
His lawyer Rudy Giuliani confirmed on public television that the intent of the "travel ban" was to ban Muslims because they were Muslims, but that they had to masquerade it as a "travel ban" merely blocking certain countries in order to circumvent the constitution. He bragged about how they had to disguise it as a "danger" argument, instead of an ethnocultural argument to get it passed. This was extremely transparent, and since their
stated intent of the ban was unconstitutional, the ruse still failed. Nonetheless, Trump's support never fell below 30%, suggesting that roughly a third of the population weren't particularly offended by his unconstitutional anti-Muslim propositions and rhetoric.
The most prevalent lethal domestic terrorist threat in the US, as measured by ideology, are
right-wing extremists, but a substantial percent of Americans
favor the anti-Muslim bans. Depending on the poll and phraseology of the questions, support for the ban
often exceeds 50%. On that note, nearly 20% advocate
stripping voting rights away from Muslims. (I would consider 1/5th of the country to be widespread.)
Xenophobia, racism, and general bigotry are real. Why is it a leap to think bigots behave in accordance with their beliefs?
