So fundamentally you're saying "Clarence Thomas would vote the way he votes regardless of the influence because he's so ideologically pure?" This is an interesting take, as the general consensus on Clarence Thomas in private life is "Ginni is his Svengali" while the general consensus on Clarence Thomas in jurisprudence is "Antonin Scalia was his Svengali". Scalia, of course, was even shadier than Clarence Thomas. I find the argument "he's a scumbag on principle, not a scumbag for money" rarely holds water, especially when dealing with political movements that indoctrinate through largesse.
I'm not saying that I support it or I'm not bothered by it. But I am saying that I haven't seen evidence that he's voting in ways that I wouldn't have expected him to vote but for the influence of Harlan Crow. I am saying that there is clear evidence he votes in ways he wouldn't otherwise vote but for the influence of his devil-wife. The last thing I'm ever going to do is hand wave away the damage that Thomas and his ilk has done and is continuing to do to the country. But again, I think it's not clear to me that his vacationing habits are really the root issue, and there's a lot else to be annoyed by.
I think where I disagree is in the idea that the water we swim in doesn't impact the way we swim. You are pretty sure that Clarence Thomas votes exactly the way he votes regardless of whether or not Harlan Crow pays for his kid's private school tuition. Would you feel the same if it were revealed Clarence Thomas goes fishing with George Soros every month? How would you feel about a "fairness doctrine" in which Clarence Thomas were compelled to have lunch every weekend with Antifa and OWS? The issue is that the idea is laughable - the thought experiment of liberal influence touching such an extremely conservative judge is rejected out of hand because it'll never fucking happen. Thomas' ideological alignment is crystal-clear, and no amount of hanging out at World Central Kitchen will change that. So why, then, do you reject the idea that Thomas cannot be influenced by those he chooses to associate with? Especially considering the massive rightward shift within the Republican Party at the ascent of Donald Trump?
