I've seen a lot of DHH content, and I'd never describe it as radical right wing.
Radical can be defined as a sharp departure from the status quo (DHH is merely suggesting a turn back to the status quo of immigration policy from maybe a couple decades ago) or as something more extreme than the mainstream view. If something is so popular it's the majority opinion, it's not radical by most definitions.
So in his mind, you can be a British citizen born in Britain but not a "native Brit." I don't see how one can reach this conclusion unless you believe non-white people to be incapable of being "native Brits" despite being born and raised in Britain.
Again, would love to see where he advocates for any particular immigration policy. The post pretty explicitly admits to just preferring when London was more white (as evidenced by linking to stats showing London is not less British, simply less white)
I don't share many of his opinions, but nothing in there screams extremist right, sexist or xenophobic.
Everyone is invited to click on the link upthread and form their own opinion!
It's also littered with references to other far-right positions, like defending someone who was tweeting out incitements to violence against trans people - "If a trans-woman is in a female-only space, punch them in the balls"
I think the average person on the left likes to believe they have the position that “all immigration is good”. In reality, they mean all migration by nonwhite people is good (see how they talk about white or near-white people in the US, Canada, Israel). It’s this hypocrisy and obviously racist stance that bugs me.
What makes Muslim migration to Europe “good” but Jewish migration to the stateless land of Israel from 1890-1948 bad? What makes Muslims moving to the US “good” but makes all white people in the US colonizers? Either everybody gets the colonizer notation (foolish imo) or migration is a human right (like it was for the million years before the modern nation-state) and everybody needs to fucking deal with it, stop killing each other and stop condemning people for moving or for the past crimes of people who may be barely related. And if you’re going to migrate: don’t be an asshole to the people there first.
How about xenophobic and sexist?
