Do you know what he means by communism?
This is a real question, not a rhetorical move.
Well, he doesn't use the word "communist" - he calls himself a "trotskyist". I admit that I'm not entirely clear on these kinds of fine distinctions between various forms of marxist/lenninist thought, in much the same way that I'm not clear on the fine distinctions between various branches of christianity - in my mind they're all just filed under "nonsense".
Christopher Hitchens is probably dying of cancer. Hitchens is a well known author, journalist and militant atheist. Having read much of his work I believe he is also a very high IQ rationalist who enjoys being provocative. He has written "I am quietly resolved to resist bodily as best I can, even if only passively, and to seek the most advanced advice."
Hitchens should be extremely receptive to cryonics. Convincing him to signup would do much for the cryonics movement in part because he would immediately become our most articulate member.
I have written to him about cryonics, but I suspect he is getting tens of thousands of emails and probably won't ever even read mine. I propose that the Less Wrong community attempt to get Hitchens to at least seriously consider cryonics. We could do this by mass emailing him and by linking to this blogpost.
Here is an article in which he talks about his cancer. His email address is at the end of the article.
