Yaron Brook of the Ayn Rand Institute explains his organization’s willingness to work with libertarians, who in the old days were ritually denounced by Objectivists:
I don’t think there’s been a significant change in terms of our attitude towards libertarians. Two things have happened. We’ve grown, and we’ve gotten to a size where we don’t just do educational programs, we do a lot more outreach and a lot more policy and working with other organizations. I also believe the libertarian movement has changed. It’s become less influenced by Rothbard, less influenced by the anarchist, crazy for lack of a better word, wing of libertarianism. As a consequence, because we’re bigger and doing more things and because libertarianism has become more reasonable, we are doing more work with them than we have in the past. But I don’t think ideologically anything of substance has changed at the Institute.
If anything, I’d say libertarians today are even more influenced by Rothbard, if by libertarians we mean actual human beings and not gargantuan policy institutions.
Meanwhile, it is evidently not crazy to have no concern whatever about civilian deaths in war.
