Indeed you read that backwards. He's saying that Thiel supporters and apologists can be found on HN more easily than on other sites. I'm not sure what to make of that claim though - he doesn't (or rather the events related to his companies that make it to the front page don't) seem very popular around here to me.

This is a more recent turn, and one that happened later than in other online social spaces. Claiming that HN leans in a direction friendly to tech VC is hardly controversial.
Scarecrowbob misused a colon, which I think is why you interpreted their post the way you did. But from the other context of the post, they clearly think the opposite.
I think they are saying they want to track the ideas of people who support techno-fascists like Thiel and who don't think that ideology is insane, and that it can be difficult to find them online
