The great replacement narrative provides the central framework for the global white supremacist movement. The racist conspiracy says there is a systematic, global effort to replace white, European people with nonwhite, foreign populations. The ultimate goal of those responsible — Democrats, leftists, “multiculturalists” and, at times, Jews — is to reduce white political power and, ultimately, to eradicate the white race. The theory has motivated multiple terror attacks, including the 2018 attack at the Pittsburgh, Pennsylvania, Tree of Life Synagogue, the 2019 attacks at two Christchurch, New Zealand, mosques and an El Paso, Texas, Walmart, and, most recently, an attack targeting Black people at a supermarket in Buffalo, New York.
As America’s demographics have shifted, the narrative of white replacement has become ingrained in the rhetoric of right-wing pundits and an increasingly extreme wing of the Republican Party. “This administration wants complete open borders. And you have to ask yourself, why?” U.S. Sen. Ron Johnson of Wisconsin asked during a Fox News segment in April. “Is it really [that] they want to remake the demographics of America to ensure that they stay in power forever?” His statement echoed others made recently by U.S. Rep. Matt Gaetz of Florida, U.S. Senate candidates J.D. Vance and Blake Masters, and, most consistently, Tucker Carlson. A recent investigation by The New York Times found that the Fox News host has amplified the narrative that Democrats are deliberately forcing demographic change in more than 400 of the 1,150 episodes of his show they analyzed.

Consider these details in terms of racial facts at making America great:
African American Workers Built America
This Black History Month, we celebrate Black workers, their achievements, and their dedication to work (a trait often attributed to white workers). We also must consider the steep challenges and structural inequities Black workers continue to face. Understanding that history contextualizes today’s fight to improve and expand African Americans’ access to higher paying jobs and economic success.
Black workers have endured a long history of discrimination, including restrictions from unions. Companies used Black workers as strike breakers to misdirect white workers’ anger and frustration. New Deal programs excluded Black agricultural and domestic workers. And 1930s “progressive” public benefits legislation such as the Social Security Act was actually pro-white legislation that neglects Black workers, especially women.
Historically, African Americans—especially women—have propped up the labor market, despite discrimination and hostility. As far back as 1870, 50 percent of Black women were in the labor force compared to just 16.5 percent of white women. Therefore, the famous wave of women entering the workforce in the 1970s applied only to white women. Black women who’ve always worked have been invisible to policymakers."

List of African-American inventors and scientists
This list of African Americans inventors and scientists documents many of the African-Americans who have invented a multitude of items or made discoveries in the course of their lives. These have ranged from practical everyday devices to applications and scientific discoveries in diverse fields, including physics, biology, math, and medicine.
African-Americans have been the victims of oppression, discrimination and persecution throughout American history, with an impact on African-American innovation. A 2014 study by economist Lisa D. Cook linked violence towards African-Americans and lack of legal protections over the period 1870–1940 to lower innovation.[1] Despite this, many black innovators have been responsible for a large number of major inventions.
Among the earliest was George Washington Carver, whose reputation was based on his research into and promotion of alternative crops to cotton, which aided in nutrition for farm families. He wanted poor farmers to grow alternative crops both as a source of their own food and as a source of other products to improve their way of life. The most popular of his 44 practical bulletins for farmers contained 105 food recipes using peanuts.[2] He also developed and promoted about 100 products made from peanuts that were useful for the house and farm. He received numerous honors for his work, including the Spingarn Medal of the NAACP.
A later renowned scientist was Percy Lavon Julian, a research chemist and a pioneer in the chemical synthesis of medicinal drugs from plants. He was the first to synthesize the natural product physostigmine, and a pioneer in the industrial large-scale chemical synthesis of the human hormones, steroids, progesterone, and testosterone, from plant sterols such as stigmasterol and sitosterol. His work would lay the foundation for the steroid drug industry's production of cortisone, other corticosteroids, and birth control pills.[3]"
