The "with cleverness we can do better than the establishment", together with the signalling value of certainly not being a vegan closely tied to the upper left part of that graph does explain the, perhaps otherwise unexpected, connection of Paleo diet and rightwing ideas from the libertarian cluster, as KarmaKaiser hilariously parodied on twitter recently:

I believe in one diet, Paleo Almighty, maker of fat and neck beard loss, improver of Game both Inner and Outer.

I believe in one job, IT, the only acceptable career. Eternally begotten of the Paul, Paul from Paul, IT from IT, true politics from true politics. One in being with the Paul. Through him all forums are flamed. For us and our currency he came down from Texas.

By the power of the NAP, he was elected by the Texans and became Representative.

That reminds me Game/PUA is also a Californian, at least in its canonical mid 2000s form, memeplex, with the goal of improving one-self's ability to hack people. It touts this can be done with cleverness, willingness to break social convention, assuming less agency from regular people and a lot of experimentation.
