Obviously any application of it to general behavior has to be heavily modified and I don't think anyone is a big supporter of it in its purest form. It could be easily used to justify rape for instance. But I think it provides the best justifications for most liberal/progressive/social democratic policies, like universal healthcare and a generous social welfare state, and most arguments against it seem to be a very warped form of deontology, which downright disturbs me. For examples I've seen libertarians argue that government programs and assistance are fundamentally immoral even if they end up saving the state money (for example the guy arguing that Medicaid was fundamentally immoral on here a few weeks ago) or krazen's entire posting history and basic philosophy of government, which has to be the most warped and disturbing form of deontology I've ever read...except possibly for TNF's, which is basically what you get when you try to justify such policies on more deontological than utilitarian grounds.
But as stated, no one but a troll would use it in a pure 100% literal form.
I wish Atlas had a "like" button for posts such as this.
And I wish Atlas then also allowed socks so I could make a pile of them for the sole purpose of liking this post some more.
