I think the real issue is framing blatant racism as a 'very right-leaning' opinion. It does a disservice to people who have normal conservative opinions on economic or social issues. We've moved past race as a social issue long ago. It's not a debate that should be had anymore. Racists aren't conservative or right wing - they're just bigots.

And to be clear, you can discuss immigration policy without being racist. In the blog post in question DHH gives his support to a convicted criminal, who is also a former member of an explicitly fascist political party and founder of an islamophobic hate group. That's not 'right-leaning'. It's support for a racist criminal. I'm unsure whether DHH is actually a bigot or just completely engulfed in the rhetoric common on Twitter these days. Either way he's a fucking moron pontificating on something which he has no actual experience of. Maybe when the US invades Greenland and starts deporting the Danes from the US he'll discover empathy.
