This i guess:

So, I have two genuine questions.

1. What do you mean when you say "anti-white"?

2. Why would it be bad if whites weren't the demographic majority in the United States?

The problem I'm seeing is that the US doesn't have a mass immigration problem. The number of illegal immigrants in the States has dropped by nearly a million people since 2009 and less than half a million people immigrate to the United States each year.

So in the United States this alt-right movement is largely fuelled by a distrust if not just a flatbdislile of people with different cultural backgrounds. 

Uh.. No. Clinton and Obama have both attacked Trump supporters to create the narrative they are "deplorable." Obama even goes overseas and mocks the people he leads, he's a garbage president.

I'm genuinely disgusted by democrats this time around. They are dividing the country.

Trump doesent have a perfect record but dems are actually pushing people away in what should have been an easy victory for Hilary.

Alt-right=White supremacy.

1. She claims America is systemically racist. She has a policy to reward millions of illegal immigrants instead of deporting them. In general, in her speech and in her policies she criticizes white part of society and promotes minorities and immigrants, often at the expense of white people. She blames whites for all sorts of problems but never says anything negative about minorities or migrants. The grave accusations against the Alt-Right in her recent speech, pulling the race card all the time. This evil woman demonizes the white man.

2. Why would it be bad if the Japanese weren't the majority in Japan? Why is it wrong that I want to maintain Sweden Swedish? No one wants to be a stranger on their own shores. No one wants to be minority in his own land.

The US simply must have a mass immigration problem if according to the latest statistics, white Americans (as in non-Hispanic whites, which is an official US statistical category) have become a minority in the US, or are a few years away of becoming minority (I do not know exactly). Black people make up only 13%, so who else is making non-hispanic whites become a minority? It must be due to immigration.

Half a million yearly is not correct. Official numbers show that legal net migration to the US has averaged 1.2 million yearly since 1990.

And on top of that there's supposedly 12 million illegal migrants residing in the USA, which means that actual migration to the US has been roughly 1.7 million per year in the last 25 years, or 44 million people. That's certainly mass immigration.

Basically a new word for neo-nazis.

Here you see the result of the Swedish education system, just like a told earlier.

Anyone who dares to oppose immigration is immediately labeled as a nazi.

The argumentation by the left is so intellectual and sophisticated.

A stupid label perpetuated by the anti-Trump movement that has no damn definition ...

No, you say that because you don't know and you are too lazy to do research.

Alt-Right as in "alternative right". It's a counter-movement that separates itself from the modern right, which it blames for losing its own identity. The modern right has allowed itself to become infiltrated by leftist ideology (such is the power of cultural marxism!) and has left the ideology battle almost entirely, and only concerns itself with economic policies.

In short, the modern right became overwhelmed by political correctness and is now ideologically confused. The alt-right picks up the ideological battle for conservatism again.

The so-called "alt-right" is just the right wing reaction to the left wing PC/SJW movement that loves diversity and dissenting opinions so long as they agree with it, thinks that the world is their safe space and you don't have a right to exist in it, and loves to label anyone that disagrees with them as a racist / sexist / misogynist etc.

This new video of a college SJW losing her mind in the presence of someone with a Trump hat on is pretty much the alt-right / SJW dynamic in a nutshell...
