Fascists need ]to convince themselves of the legitimacy of their beliefs
This process basically involves two components:
1) building up self righteous anger over nothing, usually some conspiracy about Zionists, communists, or immigrants, whatever.
2) convincing yourself that human society is exactly like the the Darwinian struggle for survival of the fittest.
Since both of these premises are really the result of the individual's subjective biases and have no basis in reality, it suddenly becomes crystal clear why fascists often take extreme measures to achieve their goals.
It's possible to justify anything if you believe in both premises simultaneously, ie,
"The jewish globalists control the world and are trying to destroy the white race! Just like in the social darwinist survival of the fittest!"
A double-whammy of sophistry is created that dumb people naturally latch onto to provide self-validating confirmation of their own personal "struggle".
I would challenge some fascists cowards to debate me on this, but they literally will not, not matter how many times I present these arguments. Probably because, deep down inside, they know their beliefs are all sophistry, but can't quite admit it to themselves. No wonder they commit random acts of violence.
As Christopher Hitchens basically proves in this interview with a disturbing character who shockingly resembles the user Dave from PoFo, fascist white supremacists invariably just end up hating themselves. Without fail they end up blaming white "race traitors" for all their problems, isolating themselves into tiny cliques of "purists", who then end up fighting with eachother over whose racists extremists sophistry ideology represents the "true" version...
(interesting to note, in this video, Hitchens also gets Tom Metzger to state that he believes whites are actaully a separate species that evolved differently than everyone else. This goes back to my second point about how important a misunderstanding of darwinism
is for these people.
You can see that nothing has really changed in 30 years, here's Richard Spencer doing exactly the same thing...
