Steve himself seems to be pretty tonedeaf- I suspect a lot more people would listen to him if he didn't post stuff on such overtly racist locations.

In the 1990s and early 2000s, he was writing for respectable mainstream conservative papers. The trouble is, once you've written too openly about certain topics, you will be ostracised from the respectable media, and these limits of acceptability are getting ever stricter and narrower. And once you've been placed under such ostracism, unless you're willing to restrict yourself to writing for free on your personal blog, you can only write for various disreputable outlets where you'll have to share the URL or column space with less seemly people.
