Guess what? It won't happen. That doesn't mean there won't be violence against white. There are racists and scumbags in every race, creed and color, and these 4 are living proof of it. they deserve to rot in jail for a long, long time.
It could happen, just look at South Africa where whites are a minority and already severely harassed by extremists in the black majority. If demographics of the United States became like that some day, then a white genocide would be a possibility.
However I guess in the US the advantage is that it's not divided between whites and blacks like South Africa, there are Asians and then Latinos who are independent from "white European American vs African American" kind of ideas.
. But many whites are well aware of the history of how whites have treated others in the past. Slavery of the African-American; the genocide of the Native American; Jim Crow; the internment of American citizens of Japanese descent during World War II.
Well, non-whites did play a big part in the African slave trade also. and what happened to Japanese-Americans during the war was really nothing compared to the stuff the Japanese did to other ethnic groups in Asia during the war. I think it's pretty pointless to concentrate on things done by whites when the most clearly the entire humanity is equally rotten. Whites just had a technological advantage for several centuries which allowed more successful domination and exploitation of others, that's all there is to it. The genocide of Native Americans happened largely hundreds of years before ideas of nationalism, eugenics and white supremacy even existed, so in the end it has always been about greed as pretty much all other nasty things in human history.
If you want to live in such fear, go ahead. As a white male, I won't live like that. I'm a human being first, and a white person second. The browning of America does not bother me. In fact, I believe, as time goes by, it'll make this nation more at peace internally.
I believe in social darwinism, if white people don't make enough children compared to other racial groups, then it's only natural selection that genes which bring white skin colour will become more and more rare. In the end genetics is pretty irrelevant anyway, culture is much more relevant thing as it so strongly shapes our way of thinking and our ideas of the world. Countries that are culturally very diverse don't last long if there's no common identity that holds them together, like being "an American" no matter your skin colour or ethnicity. Perhaps people in the US should concentrate less on race and more on the common values that hold the country together, exactly the opposite of what Black Lives Matter and Ku Klux Klan are advocating?
The browning of America will not make the nation more peaceful if people still continue to see themselves as African-Americans, Asian-Americans, Latinos or whatever instead of seeing themselves simply as Americans. Those progressives who continue to recognize race as an important factor and think people of any race should embrace their racial identity are in fact fueling racism.
