I read it. I'm not sure I agree with your interpretation. I read it as pretty standard right-wing anti-immigration stuff. He even somewhat addresses it and tries to make it clear that he's not saying one race is better than another when he says:

"There's absolutely nothing racist or xenophobic in saying that Denmark is primarily a country for the Danes, Britain primarily a united kingdom for the Brits, and Japan primarily a set of islands for the Japanese."

I interpret him to be advocating for less immigration, and maybe some deportations of criminal types. He's allowed to.

Personally, I disagree with him, but we're all adults. We're allowed to disagree and still respect each other. That's the basis of society.

He's not advocating for violence and the hyperbole some people are coming up with is way overblown when compared to what he actually said.

He is an average right-wing adult. Not some rabid fascist who wants death-camps.
