Why is White supremacy on the Rise?

Trump is a major factor in the rise of White Supremacy and White nationalism. But, I think there are many factors actually which people might not be looking at.

First of all, the white race has been supreme in the U.S. since the 1600s because of weaponry and culture and what we brought from Northern Europe. But, what is happening now even in states like California.

For example, here is a quote:
But the state's demographics in 2014 are very different from what they had been. In 2000, California's 33.9 million residents were 46.6% white non-Hispanic, 32.3%Latino, 11.1% Asian American or Pacific Islander, 6.4% black non-Hispanic and about 1% Native American.Jan 24, 2014

So, what I'm saying here is that at least since 2014 non-hispanic whites have been a minority in California 
since 2014. So, this might make people in the country more paranoid that are white. But, many states are 
not like California at all in the midwest for example. And people there might have never met a black person 
or a hispanic person or an Asian person in their whole lives and would be afraid of them because of this.

So, it's all what you are used to. For example, making friends with Hispanics and Blacks was a normal thing to
do in Southern California when I grew up. This was just normal. But, in other states the white against other 
races thing is really paranoid. 

Then you have issues like ISIS and what this has done to create anti-religious people now worldwide. 
So this also creates many problems as well.

Migrations of people not white further north into Europe and into the United States is also making some 
more White Supremacist too.

And I think if people aren't more realistic about why this is happening then it can only get much worse before
it settles down and becomes something else we are dealing with.

But, the real cause from my point of view of White Supremacy is Global Climate Change causing mass 
migrations worldwide which are only going to increase and increase and increase throughout this century.

So, White Supremacists are likely going to kill more and more people of different races throughout this century
and I think we all should be prepared for this because this is where the trends appear to be heading, especially
in Europe and the U.S. and Canada.
