We should adopt only ideas that jews had never supported. If an idea that has not at one point been supported by a jew cannot be found, then we should modify our standards to include only ideas that famous or influential jews had not supported. Keep in mind that would still exclude Christianity and National Socialism. If this is not possible to find, we should adopt ideas that jews were least known to have supported in the past, and trust with absolute faith that this standard is somewhat less silly than the others. On a serious note, the sane standard for judging any idea is by the investigation of its merits or issues, and the sane approach to dealing with the identification of an issue is not to throw out the whole idea, but to try and make changes to it that address these failings. National Capitalism, for example looks at the problems identified in libertarian ideologies and tries to fix them with nationalist policies, like keeping a domestic free market, but doing away with foreign trade, keeping a minimalistic law, but only allowing white gentiles to immigrate, and so on. Until you get something akin to the early united states or national socialism but with a much smaller government. A lot of the issues with the implementation of a good ideology is how it is abused and corrupted from its intended design, in its original state, capitalism is good, but introduce socialist elements that fuck it up like government intervention in free markets via things like subsidy and regulation, the legal concept of corporate personhood, and the obligation of corporations to prioritize their shareholders over their customers or workers. And you get a mutilated mangled abomination that is only capitalism on a nominal sense, it's like cutting off a horses leg and then calling it slow, yeah, it's a slow horse now that a leg is missing, but the original horse rode like the wind.
